Hello ladies and Gents and thank you in advance for any and all assistance you can offer. I ended up winning several items that were included in an auction lot and have been unable to figure out what they belong to. In full disclosure, I am seeking the appropriate name so I can put them on ebay unless I find a use for them first or someone here can use them. I have a general idea on the uses for a few of them such as backplates/fixturing plates, tool holders/ bushings but I have been unable determine anything more than that. I'll post pictures below and thank you again for any wisdom shared.
1)On the items which look like back/fixture plates, they are either stampedwith a K or Ketoes in addition to a set of numbers such as t5925 or 88c1-78
2) The two "bushings" are similiar to J Type tool Holders but differ in their hole size and pattern. They are stamped with their Id and BAR in addition to 622554 and 622556
3) I have no idea what any of the other contraptions are or their uses aside from the other two bar/tool holders which also have their ID hole size stamped folowed by "BAR" and the numbers 622764 and 623239. I would almost guess that they as the others are shop made or for some old turret type lathe or boring mill.
4) The two rectangular "?" Are stamped 88c1 -134 & 90. Then the other 88c1-134 & 139

The thing with the two opposing wedges looks like a split cotter locking device for something like a milling machine quill, though it could be to fit something else. I don't know what the two items at the top right of the first pic are for, but I also have one or two of those, and am interested myself in what they are for...

Thank you very much for sharing your wisdom. I would assume you're right on that and I greatly appreciate it since your search term led me to learn something new.

Ketos is a common proprietary tool steel, all that stuff looks like special tooling for die work, if I had it, I'd toss it all in the scrap.

The round piece with concentric wedges could be for clamping the quill in a drill press, mill or tail-stock. The sleeve with a hole in it is for clamping a smaller boring bar in a larger hole.
