BSA track hub?
Has anyone ever come across old parts made by BSA, specifically track hubs? One seems to have appeared in the hub box at my shop. It's very low flange, all chrome exterior, has the BSA rifles logo etched (or whatever it's called) into the shell in two spots side by side, and has an oil port in the middle. Unfortunately it's missing the dustcaps (if it ever had any) and the oil hole covering (again, if it had one). It was spaced to 127mm for a freewheel, judging by the spacer setup, but it is most definitely a track hub - one large thread and one smaller reverse thread right behind it.
Anyone ever seen anything like it? I may be able to get a photo soon...
