I recently bought a Standard Products M1 Carbine. I've had many carbines but I have never seen a barrel with this marking. Can anyone tell me the manufacturer of this barrel?
Thanks https://photos.app.goo.gl/yRF4ZJLmDEAQbc3m9 There are no marks under the barrel band, but closer to the receiver there are 3 marks. There is also a P stamped up by the muzzle.
See attached pics https://photos.app.goo.gl/np2VfnczyRkAqyBk9 https://photos.app.goo.gl/QFyjHcNGv1igYFvT7 https://photos.app.goo.gl/82tgTBecCcsfcGbo6 Appreciate the help Edit - There is also a crossed cannon stamp on the bottom flat of the barrel right by the receiver. |

Greetings and welcome to the club.
Looks like a sideways BA for Buffalo Arms.

Thanks. I've got several carbine books and info and never seen anything about Buffalo marking them that way. Really I had no idea what it was.

Hard to tell in the photo if it is or not. Here's a link to a BA marked barrel.

Is the gas cylinder swaged on? If so it could be a Buffalo Arms barrel. Honestly, I can't tell a lot from the pictures shown. Standard Products used more than one type of proof P so it can be kind of tricky

Markings found on a S'G' with a Buffalo Arms barrel. BA marked there barrels in a variety of ways. This one is marked
Buffalo Arms 9 - 1943 Ordnance bomb and Crossed Cannons Still don't have a good grasp on barrel P marks. Think this one is a different font since it is on an S'G'. |

the BA marking is from around 6-1943 and the earliest Bufflo marking. Shortly after they dated the barrels.
Early information shows Buffalo Arms barrels have been observed in the 2038xxx to 2048xxx range. CCNL 384 has a chart of all the P proofs. It was noted that there were two proof Ps for SP but the author had only observed one style. A follow up was published If the size in 64ths can be established I would say that is the early SP proof, but how it wound up on a later serial number is a mystery. Normally we would say "first in, last out" for the barrel. However the proof is applied once the carbine is built and proof fired. Do check for a second proof as Buffalo was required to proof barrels as well. Might be under a barrel band. Originally all barrels, but later the requirements were something like 100 in every 1000. I am drawing a blank when the change took place . I believe late 43. Interesting is that your receiver should have a late 43 or early 44 barrel. Could it be that this barrel was a last out or sidetracked at Buffaalo? The only other serif P I believe was early inland and IBM, neither would have used Buffalo barrels

It might help to look at the staking ( if any ) behind the front sight. SP had an unique staking of dots, either at the base of the sight or even on top of the barrel.

@Why Carbines? Are these the stake marks you are describing?
This 2,113,XXX SP has the smaller non serif "P" proof mark. |

Yes, from what I see. They either dotted the barrel or the back of the sight itself on either side of the sight key. I am not going to say they staked it that way every time, but most of the ones I have had were staked behind the front sight.
