I'm just working on a few domestic details whilst waiting for a variety of nylon spacers to arrive, for aligning the suspension. A note of caution here, for anyone contemplating building the Cromwell or Comet, I've found it tricky to fit the sprockets and idlers with the mudguards in place.

. To remove the sprockets, it's necessary to remove the gearbox first, or there's a danger of fouling- and even damaging- the mudguards. If I did this again, I'd be tempted to put hinges in the guards...
First detail. The Cromwell has some sort of access plate on the back of the turret. Maybe it's there to facilitate installing the gun. Whatever it's for, it needs to be made from scratch:

- Access plate from rear of turret
Next, some 2mm hex bolt heads. Cutting these is annoyingly like Tiddlywinks..ping..wheee...

I've learned to roll and cut them simultaneously, to avoid peppering the room with hex plastic...

- Turret access cover. Compass hole to be filled later
this is where it goes:

- Access plate in place
On the top of the Turret, the Cromwell has a small stretched oblate port for launching defensive grenades. It's next to a periscope on the left (seen from the front). Again, it's something I have to make although Chris sells
a metal version:

- Defence portal in metal
I've had to guess the scale by comparing the component with other parts (like the periscope, for instance) Scaled up on the real thing..this would make an 8in aperture; easily enough to launch a 2in grenade!

- Creating defence portal in styrene

- Little spectacle repair vice always handy..
The little vice I bought for repairing watches and specs is a little treasure. I thought I would be free of vices at my age; but I appear to be acquiring more and more of them

While that's drying, I'll bond the Mantlet support brackets to gather, and fit them in the Turret. I may need to modify them later when the recoil unit I've ordered finally arrives

- Mantlet brackets..
Then glued into the turret:

- Mantlet support pivots fitted..
I have also cut out and fitted floors to the turret storage bins (not an easy task; but they were a perfect fit in the end). The storage bins/units are meant to be glued to the mudguards/trackguards but I opted to fit them to the sides of the upper hull. This way, once the hinged lids are fitted, they can actually be
used for small scale storage

More importantly, I can put a concealed screw in the bins either side of the upper hull to hold the upper and lower hulls together. Or, I could contrive to do it with inbuilt (and concealed) magnets

- Storage bins now have independent bases
