The Comet Turret also has a 2in Bomb Thrower No 1 unit near the Loader's hatch. The unit is based on the British 2 in mortar, but its range has been limited to 150 yrds, partly because of the short barrel. It was used for close defence situations, and for firing smoke shells.
You can see it highlighted in this pic:

If you have some styrene tubing, it's not too difficult to make one of these. (I bought it, in a variety of diameters, in a useful pack from 'Evergreen :thumbup: )
A 2in pipe would scale down to 1/8 of an inch, but I used a tube with ID of 5mm- slightly large, but not too large. I cut an angles piece off the tube, and then bonded it to a wee square of styrene. The dimensions came from the blueprint.

- Bonding tube to baseplate
Then I added some Meng nuts to the base. meng nuts are resin based, I think, but I stuck them on with ordinary Revell Pro cement. They shouldn't stick, but they appear to. I didn't want to use superglue as it doesn't work that well with styrene, and mixing up 2-part Plastic Fusion epoxy seemed like overkill for four wee nuts. I'm just hoping they don't fall off. However, I did a test yesterday bonding a 2mm meng Nut to a piece of styrene sheet, just using Revell Contacta Pro and I couldn't prise it off. So...

Fitted in situ, it looks like this (do bear in mind that all these parts will be cleaned up, prior to painting):

I'm, duplicating some of these pics, because they're apt to disappear after a while, if posted from Imgur... I've seen one or two threads lately (Estniche's Tiger 1 build, for example) where most of the pics have simply vanished into the ether.

You'll also see I've added a defensive strap in front of the Loader's Hatch, and begun the process of making my own (openable) hinges from scratch, as there's no online source for WW2 Brit Tank hinges
German hinges-yes. Brit hinges -no.

Doll's house hinges just don't look right. Someday, I'll go back and correct the ones I fitted to my Cromwell.
