With my current (Camo) HL Tiger 1 that I received from RCC, includes RX18, metal gearbox, the mantel is in correct position as is the pistol port. The commanders hatch is still incorrect but it opens to the rear now. I’m not sure on the correct barrel length, what should it be?

I am thinking about the KV-1 as my next tank and I watching this thread with enthusiasm. I sure like what you've done so far dasiycutter.
