Does anyone have the type of hub and brake drum shown below? These are the hubs that were used on the 1926-1928 or so TT/I.o.M. replicas. They are different from the conventional big twin road hubs in that they use a castellated spline (the joint of which is visible) rather than a conical serration. I have a friend trying to restore a 1926 TT/I.o.M. replica, but the original hub and brake drum were lost.
He would like to acquire one, or even pictures and sketches of one to make anew. Even I have never seen inside one to tell how it is put together. The accompanying photograph I took some thirteen years ago at a LDMCC rally was a hub fitted to an DT based sprinter.
Can any one help? PM or email to myself, see links to the left, or post below. Thanks!
