What type of tool holder is this?

It looks like a professional made holder and it has some wear on it from use.  Since it does not appear to be a standard lathe or mill tool holder/collet tool, I suspect it fits some spin indexer or tool grinder device. It came with a bunch of machines and tooling from a long time journeyman machinist from the 50s to 70s era, so it is pretty old. Though I still have a lot of his old machine shop tools and equipment, it does not fit anything I still have.

Would be nice to figure out what this fits in case it is a hard to find item for some persons equipment.

        looks & sounds like a end mill holder with the taper/ slot. threaded hole for a drawbar . Here's a pretty good list that may have a match for what ya got .

No application for my SB9 or any of the fixtures/tooling for it. My vert mill is R8 and my horiz mill is one of the Atlas MFCs.

It is 4" long and the big end is 1.45" dia with a 1/2" hole in it. I assume for a 1/2" inch shank milling cutter.
The big end of the taper is 1.18".
The draw bar is 1/2-13.
The outer threads are 7/8-24.
The shaft is 0.8" dia and 3" long to edge of taper.

2-A and 4-C are close, but not a match to your measurements. Is it shop made? It could be a mistake that never got scrapped. I have a couple of my own mistakes lying around that somebody will be posting questions about in 30 years.
