I don't know why there's no bids on this. Looks like an interesting trike. I didn't know the Italians built many tricycles. This one is for sale in Worcestershire, England. I don't know the seller or anything about this bicycle.

The Seller wrote: Here we have a very nice early racing trycycle, I think from the 1950's. It says on the badge "CICLE. P.PROILETTI. NARNI" the frame is 22" and is extremely lightweight. The wheels are stamped "WEINMANN" and 27x1.25 with very narrow alluminium rims. Saddle is "BROOKS B15". Gears are "SIMPLEX" 5 speed. The handlebars are alluminium with a fancy pattern engraved in them. The rear wheels are unbraked, and the front wheel has callaper and hub brakes. This trycycle has been in my barn for the last 20 odd years so will need a good clean, but it is very sound and ridable. Thank you for looking...and Good Luck!
