I just bought my second Fuji Supreme and there are a lot of differences between the two bikes.

Bike A:
S/N = SF248676
Brake date codes = Feb '82
Lever date codes = June '82
Tubing = VALite butted 414
FD = Fuji-badged SunTour date-coded Feb '81
RD = SunTour 7-GT
Shifters = SunTour friction


Bike B:
S/N = KH203282
Brake date codes = June '82
Lever date codes = July '82
Tubing = VALite double butted 212
FD = SunTour AR? date-coded March '82
Shifters = SunTour power friction w/ratchet
RD = SunTour AR?


There are lots of other differences like the front and rear reflectors and the rims. The date codes indicate both could be 82 models but the serial numbers (and the tubing) seem to show that they are very different. Are they both original? Is either original? Any other Supreme owners out there care to share their gruppos?
