Hi folk
I'm presuming 1949 is covered by "Antique".
I've just acquired a Pultra 1590 lathe Circ. 1949 complete with a variety of tooling including some spring collets.
They are made by Crawfords in the UK and are marked 7878. They have buttress threads very similar to the Deckel S20x2.

Can anyone shine any more news on these old collets, particularly the exact spec of the threads.
Many thanks
John
