I have the same kind of safe as you - same gauge steel (thin but tough), same locking system. Funny, I don't know the name of it, but the only difference between yours and mine is mine fits kiddy corner whereas yours is rectangular. And those stupid foam holders inside with the sticky back are just such a PITA! They keep falling off the wall.
I like what you and Preacherman are showing. It gives me some ideas, and I'd better start thinking seriously about building up supplies.
