This is a very odd bike. If it's a San Remo, it appears to have a-typical rear-drop-outs..they don't look like Campagnolo-stamped forged, but, rather some anonymous stamped-out drop-out, typical of lower-line bikes.
My sense, from looking at Falcon catalogs from the 70s, is that the San Remo for Falcon may be been like the *La Garibaldina* for Gloria: many different flavors of this model were made...but not all were of equal interest or quality.
This one is extremely cool, imho, even if it is a lower-line bike, and I'm very glad it's too big for me, or I might be really stupid and bid on it. Whoever gets this one will be getting a cool piece.
My San Remo, recently restored--very nicely--by CyclArt, is Falcon baby-blue, with chromed head-lugs and stay ends, fully chromed fork, and Cinelli sloping crown. Early 70s or late-60s, with very interesting chain-stays that appear to have been narrowed in the area of the cranks, to obviate creasing them. I think it's probably the top frame in the line..forged Campagnolo drops, clean workmanship throughout.
A very fine original San Remo went recently on ebay to Eric Elman..(I think, if I remember correctly..someone here on the list, anyway)..that one was the real deal.
