And if there is no coding. I have what looks like a CRANE DR 101. Any other way to date the bike? Thanks

I can't get at my bike with a Crane on today, or I would have let you know where they are located (presuming they have one on at all) |

I have a DR-102 model long cage (third example above). It is not installed on a bike so I could examine it closely. The only mark I could find is an "8" stamped on the inside recess adjacent to the B pivot. I don't know what bike this came from because I bought it from eBay a while ago.
Another place to look for date codes is on the brake levers, and sometimes on the reflectors if you still have them.

It cleaned up really nice and works fine. I did see on the inner cage plate the letters TN stamped. With Shimano's date coding I have know idea what that means. Anyone have information on that. I also found the freewheel to be a Schwinn approved Model J from Japan. Would that be OEM? If not what should it be? Thanks |

Sometimes the lock ring will have the original manufacturer make and model. But maybe that's what says Schwinn!

A freewheel, even if brand labeled, can be identified by the type of freewheel remover tool that fits. Schwinn Approved marked components were mostly French made, free wheels mostly Atom (small splined) or Maillard (large splined). Schwinn Approved would not have been OEM on anything but Schwinn.

OK, here's a little challenge for you Shimano fans out there ...
I have a 42T chainring, on a set of 1st gen Shimano cranks (in use up to ~1979) ...
... stamped "Shimano" and "SR" in the usual place, font, size, etc., as the datecode on
all other rings I've ever seen. Clearly this is a special code, but what does it mean?
Thanks,
Rod
