So I have assembled the kit to this point. There are a lot of options, the best bet is to find a prototype and then choose the parts to match.
I chose the "Cast" turret with the two periscopes, the Stalingrad sale gun mantlet and the all steel wheels. A late style engine access hatch was used at the back.
I was just going to build it "out of the box", but ended up adding some hand rails, using the Bill Bedford hand rail jig.
Stowage and hull machine gun to be added.
