Hi people,
I recently bought a very nice Super 7 B from an ex club members son. He also has a small lathe marked up as 'F W Derbyshire' It looks like a watch makers lathe although don't take my word for that as I am a novice in this game. It comes with the separate drive pulley unit as well. The cross slide in the picture does not seem to fit the lathe, it is marked up with the name G Boley. If anybody is interested in these items I can give you his details.
The items are in SE London. All the best, David.
