I am new to this forum, so please excuse any missed procedures etc. I just picked up a mystery frame that needs an ID. Very lightweight road frame with custom paint (wasted) that looks like a repaint. Fully lugged light weight steel (looks like mid 1980's), full braze ons: pump peg, two bottle cages, front derailleur, chain holder, all cable guides, chromed Suntour Pro dropouts with no eyelets for rack or fenders. Standard thread with slightly sloped, non logo crown to fork. Serial number on bottom of bb matches Centurion: N2G0337, but components on frame don't. Cable guides are braized to the underside of the BB flanking the SN. Paint is dark metallic green with no decals, but has gold highlights to lugs and stays and the name "Kirsch". Once I figure out how to post photos, I will do so. Any ideas here?

Equipe has Campagnolo dropouts and no serial number. They were simply marked with the size on the BB. Sounds like a fairly high end frame, however.

Thanks for the response. Those were my thoughts exactly, but the serial number format certainly matches Centurion, but I can find no reference to any frame from them with these dropouts and/or a braze on front derailleur. A close look at the head tube shows the faint outline and screw holes that could match a Raleigh badge (three holes in a tall triangle) , but the serial number format doesn't match anything I can find for them. Does anybody know if Centurion provided frames to anybody else, or another company with this format of numbering? Did Centurion ever do 'custom' frames in the manner of Panasonic?
