Some relevant stuff on WW2 British AFV radios, and aerial bases:
This site is for died-in-the-wool WW2 radio transmitter nuts/ collectors: http://www.royalsignals.org.uk You could spend a lifetime clicking on all the links in the 'signals website. :crazy:

Here 'Claus Suslowicz' (possibly his right name) gives an interesting insight into how the aerial base acquired a 'halo' (protective frame) later in the War.

On this website, you can actually buy the ubiquitous WW2 type 19 British radio (still in use up until the 1960s)

In fact, there's enough stuff here - even American- to make any re-enactor's dreams come true; and to finally send that long-suffering partner oot the door permanently, or down to the local off-licence. :lolno: :D

Fantastic! Did you actually buy one to act as a sort of artist's maquette :O ? If so, then that's dedication above and beyond the call of duty (sanity too... :D ).

Edit: I was absent from the Forum for much of last year, and so I missed your Cromwell build completely. I only discovered it recently, and was mightily impressed :thumbup: I'm also envious of the advanced engineering kit (lathe etc.) that I have no access too. I have used Lathes, milling machines, and even forges in the past (Engineering in school, where I build a simple steam engine out of brass); but the best I can muster for metal parts these days would be tin snips, and a soldering iron. :| Worse still, working at PE level- with my hands and aged eyesight- is becoming one of the feats that even Hercules couldn't tackle. :D
It's a pity that the pics you posted there, in the Cromwell thread, were so small. Your handiwork would certainly lend itself to greater appreciation, if the photos were considerably more detailed detailed. (Up to 351K)
Perhaps you'd like to post a photo of your own aerial base here. You couldn't find a more relevant location. :thumbup:

Sorry - did not purchase it - just found it for sale and then lifted the pics. I used to do this when restoring antique engines from USA as I was too tight to buy the parts and ship them from the states - I used to make them. Engines now too heavy to lift and machine now so found tanks (1/16) a little smaller. Holding and turning spanners also started to prove difficult.

Just looked at the Cromwell aerial - a little battered at present. Will need to make another one for the Black Prince so could try and get round to it early. Not a lot to show in the build yet and have just ordered some alloy plate having finalised a rough plan. Decided not to follow the readily available line drawing as noticed an error with the suspension against my Bovington photos.

:D I see that the base was made by Wylex. The consumer unit in my last house was made by them but, like Crabtree and others, this company has now been swallowed up by Siemens via its former owner, Electrium.
I'm waiting for some ultra-thin brass sheet to appear from- (where else?)- China, currently. It's needed for tool clamps, and other fittings (even the aerial base). After five weeks, it's still not here.
I shall have to look elsewhere. This site looks ok:
https://modelshop.co.uk/Shop/Item/Brass ... k4/ITM1047 . Has anyone used this outlet, and can they recommend it?

If you are looking for thin brass - try Ebay - 'brass shim'. not cheap but thats where I get mine from.

You have got me thinking about the aerial base and have several ideas to try out. Give me a few days before trying Shapeways.

..a tiny update. This will be the Comet's gunsight. It's the same as the one on my Cromwell. I'll have to make a support bracket for this one. On the Cromwell, the sight is level with the Commander's cupola, but on the Comet the revised cupola was somewhat taller (to allow for the new vision blocks), and thus the sight needs to be raised up accordingly. To match the increase.

The catches on the Comet loader's hatch are different to the ones on the Cromwell: they oriented in a vertical position. I scratch- built them

Here, you can see the catches, and the bracket that supports the gunsight (which somebody's obviously purloined :/ ...) I'll look for it on eBay

When I was a boy :crazy: One of my school friends and his brother were studying for their WT Licence which was a requirement before you could operate an amateur (Ham) radio,
Their father was an ex RAF Bomber Command Radio Operator and managed to "Obtain" a Heavy Bomber HF Radio,
I would marvel at this piece of high tech (It was the early 50s :haha: ) with its big lemon yellow and red tuning knobs and dials,
Later in the service I would find myself operating C11 and C13 HF radios as well as the C42 and C47 VHF radios, But they were all a boring olive green, the only thing colourful was my language when an electrical storm would interfere with my signals. :lolno:

:D When your peepers have their 100,000 mile service and MOT, I'd heartily recommend that you use them- and some of your tank-time, writing your memoirs. :D Yes, Shaun, I am being serious. :D
All those snippets of experience, anecdotes, and recollections of (sadly) bygone decades would make excellent reading, and should be recorded for posterity (or posteriors- for critics :lolno: )
I'd certainly buy a copy, as long as it's not too pricey. I kiddeth thee not. :thumbup:
When I was at school in the 50s, almost all the kids I knew regularly swapped Iron Crosses, Reichmarks, GI stripes and much more. Swapping was the norm, and dads' souvenirs were the currency. at that time- as well as cigarette cards.
I had a WW2 Fighter pilot's helmet with RT earphones still in place.
Away from prying eyes, I'd talk to planes passing overhead with them. :shh: ...
Now I only commune with the leprechauns :lolno:

I started to assemble a version of the Mk 19 radio aerial base out of styrene plate and tube, before Enginepeter displayed his amazing expertise.
It was pretty much to scale. It began like this:
Comet-No 19 aerial base-A.jpeg
Radio aerial base

That's 1.3mm tube inserted into 3mm tube, mounted on 1.5mm styrene plate.
Then I added the four arms (1.5 mm styrene strips) at 90 deg intervals. So far- so...well, ok.
I made the 'halo' part of the radio mast's protective cage out of styrene strip. The idea was to bend the arms out, and bond the strips to the halo. Ok in principle..but the best laid plans, eh?
Comet-N0 19 aerial base- B.jpeg
Comet-No 19 radio aerial base-B

But bonding them required octopus fingers. In the end, it was all too fragile. :thumbdown:
Then these beauties arrived in the post from Peter himself (what an absolute gent, and genius!!)
Now, potentially I could have the first Quadrophonic Comet RT set in existence! :lolno:

No 19 Radio quadrophonic aerials...

Image
Which to use, hmm? Well, the ones with turned brass would be the obvious choice, but the halo might be a tad weak. The others are PLA, I think, and perhaps not as fragile. We'll see.
Then I made a mount for the Commander's gunsight:
Comet-Gunsight mount-A.jpeg

Taking photos of white objects seems to be a problem for my iPhone 8 +. It's hard to compensate for, post pic. Still, you get the idea.
Here's the unit mounted:

Finally, with generosity unbounded, Peter also supplied some fire extinguishers:

They'll come in very handy on the Cromwell :thumbup: This Forum attracts some amazingly creative, and generous, people. I only wish I could be one of them. :| :haha:

...and with the new Turret furnishings in place:

The tanks will be champing at the tracks for a few weeks now, until Christmas is over; the days begin to lengthen; and also when I can paint outside without the spray turning to icicles. :D
That said, I might find a little time to work out the layout I want for the Comet's interior control systems. :) Addiction never takes a long break :/ :D One priority will be to create a new 'welded seam' to attach to the turret roof, so that the join looks at least passable. With a detachable roof, such as this one, it's still possible to create the illusion of a weld between roof and turret sides. Currently, it's very ragged. :eh:
Hmm..and I still have a pup, and a terminal much-loved pooch to care for. :problem: Och well...ever onwards :thumbup:

Hi looking really good.


But I'm going to go full rivet counter here so be warned.
The birdcage you have on the tank is the early version and this should be a late one. Also the bottom two side parts are actually the locks that in real life would keep the hatches open. The last thing goes for the Cromwell as well.

Thanks, Tim, and do count away :D
Whilst the objective was to build a Normandy type Mk 1 (A), there are some elements from the later 'B' version. So, it's a bit of a pick 'n' mix'.
Part of the problem with the Birdcage sight here is that on some tanks, the sights were attached to the type of bullet-splash shield I've used on my model; others had a rounded splash shield, and that probably necessitated a different mounting. In the end, though, I opted for the only one available on Shapeways. Made in styrene, it would have been too flimsy (like the Aerial base I started.) Brass and solder would take too much time, and too many swearwords. :haha:
As for spring-loaded catches that held the hatches in place, mine are purely notional. :) These models, if they're to run outside, have to sacrifice more delicate details for the sake of robustness, I guess...

The Ultimate Rivet Counter...checks out the Comet's finer details with some concern

and...
The Ultimate Rivet counter- (above), with obsessive pals- won't be running alongside the Comet when it's cutting through the Highland heather :D ;) :D
In the meantime, looking forward to your Cruiser (Charioteer) updates :thumbup: have a great Christmas :D :thumbup:

Hi

According to my knowledge there were two types of splash shield.
The real early ones didn't have any and the late ones did have the one that is on your model.

Now to come back to the birdcage itself.
looking at my pictures, I have only been able to identify them juicing this type.

Image
This picture also shows a turret without the splash shield.

Image
This is the one I reconstructed, before it looked like a tank drove over it.

What I meant to say about the spring-loaded catches, is that they are still attached to the underside off your birdcage ;)
Image

Well the UK is my favourite holiday country so I might come across it some day ;D

I'll keep you up to date on the cruisers.
Just ordered a full envelop off small screws and a few servos, only need to order a extra crew member.

Happy holiday season and don't play with fireworks :haha:

Yes, Tim, I could see the catches underneath the gun sight frame; but given that these Shapeway prints are a little brittle, I didn't dare separate the parts. :O
Again, bonding the whole thing in place was something of a compromise for the sake of rigidity :problem: Then again, there are lots of pics of Comets with no gunsight at all- so, a token one seemed better than nothing; even though the design is slightly different from that on the one you were restoring. There were, in fact, numerous minor differences between Comets, depending on which company built them (Metro-Cammell et al)
Nice bit of welding by the way. :D
Yep- Parts of Britain are truly breathtaking (Lake District, Brecon beacons, the Highlands and so on), and there's much to enjoy for the military buff. You really should visit. :D
I had a good friend who lived in Oisterwijk (Brabant.NL), but sadly she died recently. I always felt slightly uncomfortable staying there with her, knowing that the town was barely
10 mtrs above sea level, and a good part of the Netherlands is actually below sea-level. 8O Gulp! There should have been an aqualung on the wall instead of a fire extinguisher. I loved the water management schemes and dyke systems, though. :thumbup: and the fact that only a couple of pushes on the bike pedals were all that was necessary to cross the entire town :haha:
On balance, I feel much safer up here in the mountains. :wave:
Cheers!

Yes I know how brittle they are, I have one of the detail sets and the real tiny parts all gone to dust when I looked at them :P
And your right almost every tank made was different.
Thanks, I had to cut almost every corner.
I'll surly stop by if I'm in Scotland, same goes for if your ever in Holland.
Well knowing we spend more than ten times as much on our water management as the UK does, so I feel save :P

Cheers :wave:
