What kind of shanks are these?

[11andrew11]

A buddy sent me this very useful link to that identifies a bunch of different shanks. The one that looks closest is the Beaver, but its OD=2", and mine =1.5".

I purchased these two facing and boring heads at auction the other day. I don't recognize the arbor/shank. They came from a machine shop that seemed to do things in XL sizes. For example, they were auctioning off an Aloris DA QCTP and tool holders. Anyway, the shank has an OD of 1.5".

Thank you.

There was also a Betts Bridgeford 80” x 300” Lathe. Can you imagine?

Only one? Small shop, eh?

Same thread question, different shank… What kind of shank is at bottom?? (R8 shown above for reference.) It’s a universal double taper “Z” collet holder for something, but I have know idea for what. If it’s listed in tools-n-gizmos link posted above, I didn’t see it.

EDIT: “drawbar thread” is ½-13

Is it tapered in the middle? I thought it was at first, but maybe its just an illusion. Also, it's interesting that it has the three shinier rings around that middle section. I wonder why. Sorry that's not an answer. I'm just spit-balling at this point.
