General Information
This is the made-for-Schwinn USA version of the Success FD.  Although some nut & bolts are simplified to rivets, the mechanism (and patent #) are the same.

It also has that spring plate / gate of the later versions that aids large ring changes.  I would presume it an excellent performer.

This one is NOS and NIB w/ the Schwinn catalog number shown.  FWIW.
