This is a survivor bike. The frame seems to be the only existing original finish anodized P.K. Ripper. There have been others known, but due to degradation of ano, others were refinished or polished out. Former SE Factory rider, Derek Brown does have his factory ano blue DB IV. There might be others out there, but at the moment, these seem to be the only known to the vintage bmx community. Rod Beckering also confirmed the existence of these ano frames, which is notable because Scot had forgotten about them. Rod is known for his memory, so that was important verification.
