My Gios frame has no serial number on the bottom bracket. The vintage is roughly 79 by the fork design and frame details seem identical to those on the Classic Rendezvous site pictured as the white Super Record. All tubes are well mitered and the bottom bracket is engraved with gios as are the seat stays tops. All details are again the same as the white one on the site which does have a serial number. What's up? Any ideas? (P,S. there is a 57 stamped on the bottom of the bb and all the decals are in place including the columbus and the professional)
