I have seen such a set (maybe the same) one or two years ago on ebay. I don't think that it is real. Only one thing: The accessory shoe shows a number starting with 54, but the camera is a KIEV 4...
Yes, set is most definitely has aftermarket paint and engravings. In right box it will looks stunning! To make such set you have to take lenses and camera apart put new engravings, paint and then very carefully put all together and align. Very hard job. IMHO totally worth money what set was sold.
