The pictures are probably not revealing everything but here a couple of more things I've noticed,...
Snare: Die-cast hoops, wrong position of the tone control knob, wrong strainer
10" tom: Camco never did 10", no reinforcement rings
12" tom: Hoshino Camco lugs ???
14" floor tom looks like a conversion, Premier style hoops
20" bass drum, probably the most original part of the kit but why call it virgin when there is clearly a (non-original) tom mount installed ?
I agree with Cruisin,... the parts, that's where the value is.
