Vintage Shimano MF-Z012, 6 Speed Freewheel, 14-24T with standard English hub thread 1.37 x 24. Prior to sale I have cleaned, degreased and lubricated the freewheel so it spins well. It would however benefit from a complete strip down and re-grease like any vintage freewheel. The teeth are square but as expected from a vintage item it does show signs of wear and has some surface rusting and a dulling of the metal/ patina. I do think once the freewheel has been fitted and it has been used for a while that the surface rust will come off to a large extent. Overall a very nice component that would be a positive addition to a vintage bike build project.
