Can anyone identify these jaws?

Nabbed off eBay with some other bits and bobs. They are large lumps of hardened steel, maybe come in handy for use in a jig.

Just wondering what they might be off...

There's a prize...

Some die stocks have jaws especially pipe threading stocks to help keep the die right while threading, maybe off one of them? but not presto as that's what I have and it's different.

It certainly seems designed to locate accurately but if they were regular 3 jaw chuck inserts, I'd expect to see two mounting holes...

I'll have a look for threading stocks thanks.

Rear dies for an Asada pipe threader ? used to help line pipe up with cutting dies

That's a very specific guess, what makes you suggest that? Google isn't finding anything similar.

Best I have found yet is searching "rigid tongue and groove chuck jaws". But nothing with the single hole. Maybe an older Burnerd chuck...

Had an old pipe machine in for repair Asada no spares available used by ANIMALS never cleaned dies out trying to do full depth cuts in one pass on 2 inch pipe, 20 ft of pipe hanging out of steady ring on back of machine the jaws were something like those shown so it is a guess
