I have 2 NOS regina extra futura sets, in the original wood box. It includes 13-18,13-21 and 14-24 cogs, and cassette unit with tool for changes. I think they were quite expensive new, and did not find a viable market in the early 80's. I am going to list on Ebay, but will sell to list for $100 each and $10 shipping in us. Let me know if interested, i'll forward photos. thanks
