Might pick up a late 80's Guerciotti GPS 7200-Pista. It is a 50cm.
Heres a link to the catalog of that model
Just wondering how much it's worth/what to offer. Here's what the owner has to say about it:
"Mine is bright red with yellow, bone stock with Suntour Superbe Pro Pista everything (2 sets of wheels - one tubular, one clincher). Cinelli bar/stem, perfect color-coordinated tires. Absolutely showroom perfect in every aspect except the original yellow bar tape is a bit faded now from sitting so long (can't bear to replace it as it is original)."
