Could someone help out with these collets.
One collet is marked WW
Body diameter is .439
thread 9.2mm - 0.80

Thanks Gus

Looks like collets I used to use on a Derbyshire Lathe. WW is correct, then.

The dimensions for body and thread are wrong for Derbyshire WW or Magnus-Elect collets.

Webster-Whitcomb (WW) body is 8 mm and thread is about .270"-40 TPI vee form.
Magnus-Elect body is 10 mm and thread is M10 x 1 mm buttress form.

Looks like it might be Springfield No. 3. The body is .440 with a thread .365"-32 TPI vee form. This is a rare collet for a rare machine.
