Not sure if this is the right place to post and ask this. But can anyone identify the maker of this rotary index chuck? It was on a Bridgeport mill and has 3 index plates with it.

I’m interested in figuring out who made it to see if additional index plates can be found.

No manufacture plate was seen.

It appears to be an early Kearney Trecker to me. I have one of its brothers I picked up, I use it from time to time. My plates have a collar on the back side. They are not just a flat plate.
Finding additional plates may be a challenge.
 
If it's a K&T, I couldn't find anything that looked like it at vintagemachinery.org. And the plates didn't have a collar on them, flat on both sides.

Catalog cut is from K&T number 19, reported to be from 1917. Included a pic of mine with a plate. I am not a betting man, but if you pull the plate from your dividing head, it looks like mine.

I think that’s close, but not quite it. I took some more pictures.

I also noticed what looks like a serial number plate on the back. Not sure if that helps.
