Which M1 Carbine to pick?

[Hpmaster]

I have an opportunity to get a free M1 carbine. There are 5 I can choose from. They have not been dug out in quite a few years and I know there is one Rock Ola and the rest are Saginaw's or maybe one other make. These are all in very nice condition as they were old DCM or very early CMP club guns from quite a few years ago. No I don't get to trade parts around, I did ask LOL. Never been into carbines what should i take into consideration. Thanks in advance.

update
Here is what I got to choose from talking to the guy who just got them out. 2 Winchesters one has an Inland barrel, 4 rivet handguard, the other has high wood more dents no bayonet lug original barrel 2 rivet handguard. 1 rockola no bayonet lug 2 rivet handguard original barrel, 1 underwood no bayonet lug seems original. 2 Saginaws with bayonet lugs and 4 rivet handguards. One Inland he says looks like a canoe paddle with a mix match of parts and bayonet lug.
