T-Mar , this doesn't seem to fit either DB or Centurion formats you have previously noted. I would guess its 89 with month k so 11-89 build? seems plausible?
Actually, that format has turned up on Centurion. I don't know the identity of the source but it's consistent with the manufacturer of the Centurion Ironman Carbons and some of the very late Centurion Prestige. However, this is the first time I've seen it on a Diamond Back. I agree with the interpretation of the format.
