I must add the comment that the interior of the Academy Tiger I kit is far more complete than the 1969 vintage 1/25 th scale Tamiya Tiger I kit.
Recently, aircraft builders have been getting some very nice kits with full interiors at modest prices - for example: the ROG 1/72 B-17G..
It would be nice if more armor kits had interiors.
I've been considering purchasing and building some 1/25 Polish paper armor kits simply because they have interior details.
