The site is performing very poorly today, so I am entering small amounts of data, saving, then adding more.

Hummer contacted me earlier today about the ID number on a bike posted for sale over at the CABE. Here is the bike:




This one has a 1971 Campy derailleur to somewhat confirm the date, and a large "RO" stamped inside both dropouts.

We have two additional Supercorsa frames that are easily accessible. This is a red metallic frame that has basically identical decals and frame characteristics:



This one does not have the large letter number combo stamped inside the dropout.

This is a flat orange Supercorsa frame with identical frame characteristics and similar decals (but seat tube decals are mostly missing):



This has "R4" stamped inside the dropouts.

I could not find any other identifying numbers on these bikes on the bottom bracket or other places where a serial number might usually be found.

The collector of these bikes told me he liked to collect one of each color for a catalog year, so it makes sense these would all be the same year.

We have a half dozen or so TdFs as well, but it will take time to pull them out and remove the wheels for pictures so I probably won't get around to posting that information until next week.
