I realize they couldn't have done this all in one piece and it looks like the chassis and interior were separate but soldered together. The seats are soldered? to the bulkhead. The door panels look to be separate but they have less gaps than the picture. The passenger side above the door handle is the only place I can get a toothpick through. The body lines do not go through as you can see some places on them that are flush so may have been soldered together before dropping on the chassis. It is a heavy weight and the body is one solid piece, that is where I came up with it "looks like it was made of a solid brick of metal" I am very happy with the purchase of this unique piece and appreciate any input!
