I know this has been discussed before but there's a few things I haven't seen answered.I want to model a prototype, V2 and have seen the Bovington pictures. was the loaders hatch on the rear of the turret always missing? Also the exhausts I have seen show that they TEE off to the side and have a flange on them. The left exhaust TEES to the left and the right exhaust TEES to the right. Were they always like this? I am not going overboard and worrying about the 18 tooth sprocket or tracks. I am just trying to get the basic shape down. Were the early side skirts always there? Thanks---John
