I've recently got a Legnano for a great price at a local auction and would like some help dating and valuing it. I have Googled but can find little to help with dating. I have read that 1953-1956 is a good possibility. The only serial number I see is 275 on bottom bracket- also looks like a personal owner serial number was scratched above it unless that's by the Legnano also. Ton of Campy including headset, seat post, and pedals. Other serial numbers I have seen online for Legnano Roma Olimpiade is usually a six digit code beginning with two letters.
