Ive recently bought a old RC kit and after searching the web and confirming with my recources at Yamaha I can say mine are wrapped Standard Recording ''GA'' kit.

One line had lacquered exteriors and stained interiors-the Recording Customs that we all know. The other line had wrapped shells and unstained interiors. That line was called Standard Recording. The Standard Recording wrapped finishes were black, white and red and matte natural (no wrap). The glossy natural was part of the Recording Customs, since it had a clear lacquered finish. After a couple of years, Yamaha discontinued the Standard Recording line, and just had the Customs.
Check also if the shells have a diagonal seam (from Yamaha's Air Seal System)
It could be the grommets (saving the wood in the badge hole) where damaged and somebody removed.
In the worst case everything BUT the shells are from a Yamaha RC/Standard (same hardware other badge number) so you would have some value to ;)
