Among a box of parts I have acquired is a J Moyne hub that I have not
seen before. It is a rear hub, and appears to be similar in function to
the 1940s/50s Baylis Wiley unit hub which I am more familiar with, in
that the freewheel is built into the hub. The main difference to the
B-W hub is that instead of threads for sprockets, it has an octagonal
block onto which either suitable sprockets or some form of adapter fit,
to be held in place by a lockring. The hub can be viewed at
