This is a very strange collet. It looks a lot like 5C and the same
approximate size, but it is left hand threaded and the thread is very
coarse.
It was in that chuck.
Would anyone have any idea what are those called???

Omigod, you come up with some weird stuff. I think you have a Crawford
collet/chuck set, which uses a big T-handle key in the collet chuck to
tighten it. It had a product name, maybe "Tightgrip."
Odd stuff. 'Haven't seen one for 30 years.
Yes, the name is "Trugrip". And so, you think this is called a
Crawford collet?
I have not seen this stuff in 40 years.
