Thanks for all the suggestions guys. aj, I will remove the rounds from the inside of the hull. It makes sense that there would not be anything left.
doog, I've taken your advice and taken another wheel off. Instead of showing another hole, I've left a mounting rod in place to show a bit of variance. Now, what would you suggest as to the positioning of the wheels that fell off? Since the whole tank will be dipping down a bit in the nose, due to a slight elevation of the terrain, I could place one of the wheels very close by, as if it just fell off, while the other was blown off.
panzerguy, thanks for the diagram. I actually was not really planing to have 'much' debris. There is basically the rear engine cover, which I plan to have at the back, the drivers' cover, and one of the turret hatches. The wheels will also have the 'just burnt' look via ash spread around them. I see that in the diagram, you moved the the signpost to the front. Just out of curiosity, how come you turned the motorcycle around?
I am just waiting for the epoxy glue on the wheels to set, so as soon as I can stand the tank up on its own wheels, I will apply these slight re-arrangements and post the pics for your further scrutiny.
