I'm cleaning out the garage and passing along the interesting stuff to more worthy restorers. Up for auction on eBay just now is my complete holding of Regina (Extra) Futura interchangeable cog sets. These were introduced in 1983 and endorsed by F. Gimondi. The sets are incomplete but enough to display plus build up an on topic Italian bike.
Auction ID: 190307002038
I never managed to come up with a suitable project to attach to this stuff. I hope that someone on the CR list has the opposite problem. If a CR member wins the auction, mention it to me after the dust settles and I will ship for free (in the US, and a $10 credit towards overseas shipping).
