I see my serial number 249871 is in that sheet (thatnks [MENTION=342124]rustystrings61[/MENTION]) and I can add that it was originally painted orange, no chrome, all 531DB, has Campy DOs and forkends, a Vagner flat-top crown, Georg Fisher sand-cast BB shell...does the SN indicate circa 1975? That's what Craig Griffith thought it was when he sold it to me.
