What are these? Are they even tools?

[Magnum440d100]

Going through the tool box that I got from a friend. The boxes were his step dads who was a toolmaker when he first came from Holland in maybe the 50’s(?) and then he went and worked for Lockheed Martin/Boeing, etc later in life, retiring in appx 1994....

So.

What are these, are they tools, and are they worth keeping around?

Thanks in advance!!

the rectangular ones with holes look like t nut that slide into the grooves on milling machines etc. a bolt would go thru the hole . used to clamp stuff while machining

I see T nuts, on the bottom is a reamer (yellow cover) and below that some lathe tool blanks. Up top I think the cylinders with the hole through them are truing sleeves for a hone (they should be cast iron and not hardened).

Possibly crimp dies & pushers?

Long story short - if you can't find a use for them, then no. Lol

That orange handle looks like the handle from an Ullman mirror.
