Saginaw general motors barrel

[jbm]

Can anyone help me with this barrel? This appears to be a new barrel never installed. It is marked SAGINAW S.G. DIV GENERAL MOTORS it is not dated and most barrels that I have seen have a date on them. Any and all help is greatly appreciated! I can not see how to post pictures of it.Attachment 97140Attachment 97141

I am not a carbine guru like most of the guys on here are but I do know enough to tell you that all carbine barrels were not dated and are still usgi barrels.the pros will chime in soon and give you your answer without a doubt.evidently I will learn something new here too because I noticed the picture you posted of your Barrel, I did not know M1 carbine barrels were left roughly machined. The picture of that Barrel reminds me of my Mosin Nagant barrel which is a 1943 wartime manufacturer where they did not take the time to machine it smooth and just left little lines like pictured on your Barrel

Is that an ordnance bomb stamped on the cas cylinder? Looks like it's been sand blasted and parkerized. Could have been done after the fact.

That is a ordnance bomb, I did not even see it. Were these stamped on all barrels? Also, the bore on this barrel is absolute perfect.

To me with barrel in hand does not look to have been blasted and parked, the machining marks are too prominent and I would think with sand blasting they would not be.

Maybe right...

BAR, did they leave carbine barrels unmachined and not smoothed?I know Russia did their barrels that way during the war because they were just worried about cranking them out and not finishing them up but I did not know American made carbine barrels were that way.

[browningautorifle]

It's just the parkerizing that makes it look rough. The machine marks look correct. If it were rubbed with oil and handled a bit on a carbine, it would be smoother too... Just not sure if it's WW2 new, don't know for sure.

It does appear to still have a long skirt. I could be way off but I thought they switched to the short skirt fairly early on.
