We recently had Schwinn Paramount dropout adjusters machined and cadmium plated, a faithful reproduction of original ones found on Paramount track bikes from the late 1930s-late1950s. Schwinn originally copied the design from quality British made adjusters, so they are interchangable with BSA, Chater Lea, and other British hubs of the time.
They are $100 a set.

How can you acquire a set of these?
