The have 3 distinct "steps." The picture isn't great. I'll post a better one.They kinda look like they're MT taper reamers. Congratulations on a good score!

The hand-etched part number smells custom enough. I wonder what they would have been used for.Good buy! Sounds like you got your money's worth, and then some.
Those last reamers are curious. Definitely not chamber reamers (which are almost always (always?) straight-fluted), but also not taper reamers, which is what I thought before looking harder. Perhaps custom?

I have said Chinese Amazon HSS endmills and I think you're not being quite fair. I used one to cut a 6" slot in plastic and another to cut 4 holes in aluminum, and both of them have >70% life remaining.A quick search on Amazon for "end mill assortment" show about $17 for 10 pieces of Chinese HSS, guaranteed to last a least one cut through soft pine. (That's not actually true. There is no such guarantee).
I don't have a sharpening jig but I plan to make something.I'd jump on that. If you have a sharpening jig, you did spectacular.
I like the little tool box...more pictures of the box please.
I was only joking about my experience with the Chinese endmills. I do have some and I have used them to cut plastic and aluminum but they're still like new. I haven't used them for anything precision so I don't know if they're absolutely straight or within spec or anything, and I haven't tried using them on steel (and don't plan to)I've had no issues with my Chinese end mills, but I've mostly used them on aluminum and brass. The machine pushing them probably makes a difference too, a 2 or 3hp mill will be more demanding of an end mill than a fractional hp mill.
I'd lay money on that box being a Kennedy.I estimate that it, like the end mills, has managed a longer life than I have, so maybe more credit is due, but in my opinion it's pretty unremarkable and you could buy a better one at HF. I can't find a brand name anywhere on it and it's made of thinner sheet than I would have the gumption to make a toolbox out of. I assume it's either old asian import or the cheapest American made that money could buy prior to the proliferation of Asian imports. But beauty is in the eye of the beholder, and you asked, so here are some pics:
