A lot of vintage watch maker lathe 3OS collets used on Rivett lathes and possibly others.

Over 60 each collets, (32 different sizes), 18 step collets, a collet closer (the closer tube has been cut and rewelded, doesn’t affect operation of the closer), a 3” 3 jaw chuck branded Whiton and another item I don’t know.

There is one collet chuck stamped as Hardinge brand, many collets marked as A. W. T. Co. brand, some unmarked.
