As Issued 1944 IBM M1 Carbine

[majspud]

Hopefully you all can confirm the title statement. Vet bring back from Korea; provenance to follow. All IBM save unmarked oiler, band, and recoil plate. Unusual push button safety for April 1944; SN is 90,000 units from end of production in May. My IBM magazine, mag pouch, and Engineer's holster. I'm a lefty, so the pouch is backwards. Carbine had been together a LONG time. Gummed screws and works, grit and grime, bolt springs gunked up, and the interior of the bolt was like varnish. Bore is bright and excellent.

Nice lookin' carbine regardless...

I'm probably not the only one that doesn't get overally excited about the term "vet bringback." It's simply too hard to prove with and especially without any paperwork. The gun itself appears to be right. How is the right side of the rear sight marked? If it's marked IRCO (maybe drawing number too) then there's a chance it could be original to the gun. If you could add a picture or two of the staking of the rear sight we can tell if the sight is original to your gun. The type two barrel band on your rifle is one of the ones IBM used near the end of its production. I suspect the receiver is one IBM made itself since I don't see an AO on the receiver heel. Verify this though as not all AO made receivers were marked AO. If your receiver has a the "wide" tang then AO made it. The only other thing I see is that the stock has been overally sanded...in my opinion anyway. I like it in the long run. The only possible thing you could say is the rear sight and it's possible it could be correct. Thanks for sharing!

The rear sight looks like an H in a shield (Hemphill)

You have a nice looking carbine.
I have seen "H" in shield milled on a few I.B.M.'s.
Enlarging the right side photo it shows, as Bill says, a pressed sight with "H" in shield. Check the stake marks, or if you can take a close up photo of the rear sight base.

It sure is, Bill. If I'd blown it up some I could have noticed it myself. My thought now is that the rear sight could be a replacement (field modification maybe). Hopefully he will post some pictures of the top of the dovetail. There's one picture already that comes close to showing that area, but it's taken from the rear and it's hard to tell from that angle.

Rear sight is "H" in shield. "H" also on left lug of bolt. Gunboards is saying L.R.Co. 7160060 ones were the most common, but a limited number of "H" ones were used. We have a small "G" under the "H" on the bolt. New pics added to the first.

On IBM they didn't they start to use milled Rear Sights with the "H in a shield" at or near 3,964,000 i think the SN on this Carbine 3,024,924 , but this is a sweet looking Carbine.

[majspud]

SN is 3924294.

The "H" in shield sight people on this site and others are referring to is the type II milled version. The sight on your IBM is a type III stamped version. As stated some type II "H" in shield rear sights did appear in the 3.93 range (at least). If you could post one or maybe two more pictures of the rear sight from the top it should tell us if your sight is a replacement or not. When you take the picture(s) make sure the sight is adjusted all the way to the left so staking or index marks (possibly both) can be revealed.
