I'm doing this using a Komplekt zip turret,as all the parts are in the kit for the hull to be built without Finnish modifications. I just noticed there are 2 kinds of radiator intake cover supplied, these are the ones either side of the main engine hatch, parts E5 & E8 which have angled inner corners (these being extra parts in the BT42 kit)and parts B22 & B23, which are part of the original BT7 model35 kit. Which should I use? It's not very clear on any plans I have.
The Komplekt zip turret is very nice by the way, but I think a little too narrow.
With the angled inner corners, otherwise the turret wouldn't fit.
