Interesting. To me they don't look like exact copies, in terms of being mechanically copied in some way, as there are some differences, and if they were hand sculpted, it would obviously look like the 1/35 items were used as models for the 1/72 version, which is an odd thing to do... but is it illegal?
(In terms of the "reality of war" - yes, indeed, although of course only the ones that have remained intact, just like in old movies.)
