Authenticity

I'm a new member and have learned a lot from you fellow members and I am very grateful as you have saved me much time and money. Especially money. What I have discovered as there are many sellers who either don't know what they are selling and therefore unintentionally misrepresent the rifle or just plain think they can pull a "fast one". This is a post from a Gun Broker auction and I'm trying to determine if the AA in the serial number represents the Aniston Arsenal and if it is a re-armored rifle. Other features also make me question whether there is anything collectable here. The seller claims it is collectable. I'm not trying to be a trouble maker, just looking for facts. 

Thanks, you confirmed my suspicions. I have four other M1 carbines and I'm doing the data sheets on them to find out just how authentic mine are. I know that I will have a few mixed parts, but I also know I don't have any weird rifles like this. 

I don't get the impression he's trying to pass it off as a USGI M1 Carbine, he's just using typical sales pitch type description. Judging from the serial number, it's an Iver Johnson M1 Carbine (My IJ has a AA prefix in the serial number). One area in which the description is blatantly wrong is in the caliber. If you look at the muzzle in photo 25, it's pretty obvious that isn't a .30 caliber hole in the barrel. It's probably chambered in 5.7mm Johnson/.22 Spitfire.

Hmm, good to know that the seller did his research!

I can’t see IJ letting a 30 caliber marked as such get out the door with a Johnson barrel on it, but anything is possible I suppose. If it really was a Johnson, it would likely be bidding higher than it is now. There is somewhat of a following for the Spitfire.
