WIP but having trouble figuring out exactly how the gun sits, esp. how far forward and how high . . . Bronco version differs by not having internal shields so gun shield sits almost flush with side plates; have seen Trumpeter versions mounted in multiple ways in different web posts. In Trumpeter instructions (and reference photo), the gun shield actually appears to be lower than compartment walls, but seems physically impossible with kit. Doesn't help that instructions show baseplate for Pak 40 installed in the wrong direction. With only a few reference photos (maybe 4?) available, difficult to determine what is correct, but I guess that's what you get when there were only about 24 or so originals.
