I have decided i cant stand the look of the mount for the gun, the mantle sticks off the casting on the turret way to far forward. In comparison of photos, the mantle should sit about half as close to the turret face. The curve of the casting gun mount should be much more shallow and gentle. Im going to take my new gun mount apart and file down the high curved castings of the 105 mount.
Just look hard at my middle photo in first post. Then go look at a 75 sherman photo broadside on google and my model will hurt your eyes.
