Post WWII M1 Garand Barrel questions

[Kaydee]

I have a M1 Garand barrel that is marked -D6535448 42 A152D on the top of the barrel and S-A-8-51 on the side. Scott Duff's, "The M1 Garand: World War II", states this Part # or Drawing number was first used in 1941, and I think the 42 in the drawing number means it was made in 1942. However, the side markings shows a manufacture date of 8-51.
Scott Duff's, :The M1 Garand Post WWII", states that Springfield produced Receivers on January 1952 with serial number 4203210 and a barrel marking of 9-52. The barrel Drawing Number SA D6535448.
I have been told that my barrel was a replacement barrel. If this is true, could my S-A-8-51 barrel have been installed on receiver with a serial number 4,297,000? What Springfield Armory Receiver Serial Numbers were used in 1950 and 1951? Were those Garand's used at the beginning of the Korean War WWII and Post War issues.

What is it leads you to believe the receiver wasn't just re-barrelled by someone since manufacture? That barrel was just chosen as suitable? My barrel is D38448-7 Rep-19. It's 1941 issue. I have Duff's book and don't know where you'd have read that about the drawing number. The one you show is marked with the later drawing number and the date seems correct to me. Yes, there were lots of WW2 rifles used in Korea. It was only five years after... You'll see illustrations of early WW2 features like forged trigger guards and lock bar sights still in the units. The later production lines were set up to supplant shortages.

You are misreading the part number -- the 42 does not mean 1942, it means the 42nd modification to the original drawing. Those mods could be something as minor as a change to one of the milling steps, a difference in heat treat, any of dozens of small things that did not change the configuration of the barrel.

Serial numbers of 3 million and below would have been in use in 1950 and 51. Some of these same rifles, assuming they made it through two wars, could have still been in use in the post war period, if that is what you are asking. Of course many of them would have gone through an arsenal overhaul after WW2 and, of the original rifle, only the receiver might remain.

Jim, The barrels were all revision 7 from 2-41 to 12-41, I just did not list every month.

On the Lend Lease rifle with the S-A 8-41 barrel in your photo, do you have the rear handguard band with the groove ?

Roger that...

It appears I didn't take a pic of the grooved handguard clip, but yes, I have one. This LL is all complete...front sight seal and round firing pin...
