I removed this vintage item from an off-brand bike. It is intended for a 10 speed bike. It is marked "Made in Taiwan". it is in good condition. The springs and jockey wheels all seem to be in good working order. It would be great for the bike collector or to finish your clunker build. I am selling this item as is with no returns, so look closely at the pictures. No international sales. Thanks for looking and please stay safe.
