Ebay.

I'm not sure, but I think the cranks in question are copied from Williams C34 and C1000. Earlier ones have small, threaded bolt holes; later ones have large smooth bolt holes. The Williams chain rings were made in both 1/8" and 3/32" widths, and as small as 32T.

This photo is of my Norman Rapide, from 1950. The bolts have a square head and thread into the ring from the other side.

I'm pretty sure I have a 34T and a 38T that I'm not currently using; I'd have to check exactly what they are.

See here for more detail.
