You piqued my curiosity
The frame number (assumed was on the bb) appears to have been ground out
Most odd
Would it also be stamped somewhere else (like steerer tubes are on road bikes) perhaps?
The inside of the rear dropouts are stamped ‘C3’ if that means anything at all?
hello, 1993 was the only year they did this odd paint/decal mash-up, the frame number will tell you what model it is. RB thread here, 4th entry;

Fantastic frames.
Pedant satiated ;-)
