The Smallest Minority on earth is the individual. Those who deny individual rights cannot claim to be defenders of minorities. - Ayn Rand
A friend of mines buddy worked at IBM. He brought an IBM M1 or Garand, I don't remember which, into work one day. IBM management was not pleased, to say the least.
He innocently asked "What's the problem (pointing to the mfg. stamp) it's a company product."
Wish I'd been there for that.
Order mine a day after you, received them a day after you; looks like Ky Imports is pretty consistent on getting stuff out the door.

Quite a bit of variation in the details of each depending on manufacturer.
No rust at all; small amount of cosmoline on all of them. Look like just what they said they were: unissued original magazines.
Now I just have to get something to use them in :-).
I got mine from Cole Dist. this week. Not sure of the exact day-the (small) box was left on the porch, by the front door. And my family comes and goes almost exclusively through the garage, so we didn't notice it.
I got the 'used' ones, but aside from a few scratches, I'm hard pressed to describe them as used. Not even the usual edge wear you'd expect from being carried around in mag pouches. And all coated in a thin layer of packing grease. Oh, and all were blued.
Only marking I recognize from your list is International Silver (IS).
I've got a friend looking for some. How much do you want for them?
Not for sale! The IBM's go on sale from the CMP NEXT October! (I need to take a remedial calendar-reading class.)
