Hi Mike, I certainly have found plenty of holes and funny shaped brackets and it's a on going job to identify and put a name to them. As far as the smoke generator stowage that one is still a mystery to me but I'm sure it will be solved just like all the other have been here.
The traversing gearbox is progressing and I'm understanding the drawings more and more each day. One thing I have noticed when I am under the turret with the gear box and test fitting it, it would have been a real problem when the crew would have been bending down getting supplies from the floor stowage, they would have had to hit their head so many times on the handle. When I get to that stage you will see what I mean.
I have got the brake shoes fitted but need to make the handle and release mechanism before that part is complete.
