Its a rare occasion that I can add anything to a discussion on this board. Thanks for the kind words. if anything the bottom is easier than round panels right?

and yeah I couldnt decide on open or closed tops, but the original pic looks like the soldiers foot is blow hull level, so i took a guess and subsequently had to build an interior lol. i wish I had seen the drawing you posted, as I'm sure I would have gone that route.
keep me posted!
