After further thought, what do you mean by old? I picked up a late 90s Marin Verona frameset (Italian built by Billato with Columbus Thron steel tubes) and surprisingly it has room for 28c tires. It also has fender eyelets, but I imagine you'd be limited to 25c or smaller tires. So, if it's primarily steel you're after, you may be able to find something modernish that will suit your taste.
