A NOS vintage Shimano Lark 5 Speed derailleur. This derailleur was used on many muscle bikes including the Murray Eliminator Mark II and F Series muscle bikes, and the Sears Screamer, Huffy Rail, Judge, Slingshot, and Twin Stick. The chrome is mint. The rest of the derailleur is very nice with a nice gold Lark logo plate that has only a few shelf wear marks. I cleaned and detailed the derailleur and filled in the black area in a few small spots where it was scratched. The areas I filled in won't be noticeable when mounted. Includes the hard to find plastic dust caps for that finishing touch for your mint original bike or for your best restoration. Please email me with any questions.
