Unfortunately for the asker...I cannot remember what the other two Garands were...(I called them this morning and they were down to one)
It turned out to be a Century (yes, yes...I know)
Still, I cram-researched, got there and field-stripped it, and was lucky enough to have a guy there that knew a bit about Garands.
Most of the parts are Springfield Armory, with a Beretta barrel, and a C.A.I. cast receiver.
Not much collector value, but it should be a decent shooter, which is what I bought it for. (oh...yeah...I did buy it, lol)
I know the owners well, and if there are any major problems with its first outing, I'm confident they'll work with me on doing a fair exchange for another gun.
I've already gotten it home and detail stripped it...found out that the internals were packed with cosmo (which I consider a good thing). All the major wear points on hammer, extractor, etc. are in good condition.
I do not, unfortunately, have go-no go gauges for the gas cylinder, so I guess I'll take my chances. If I have a few FTF's, I guess I'll know what's up.
Overally, I'm happy so far...I'll report back after I actually put a few live rounds through the thing.
P.S. Oh...I do have a -single- box of 30-06 labeled "for M1 Garands", but I also bought a couple boxes of more modern ammo...should I be wary? The other ammo is a heavier grain...180-something as opposed to the 150-grain M1-specific ammo.
