m1 garand barrel markings

[weaksauce867]

im new to M1's and i was doing some research on my M1. it has NM sights and oprod. When i looked at the barrel and gas chamber to try and determine what type of barrel it was i could not find any marks on the barrel or gas chamber. If anyone has any informaiton on how to determine what type of barrel and gas chamber i have it would be greatly appreciated.

For the barrel look on top the muzzle behind the front sight, if it's a national match barrel it may have an "NM" stamped there. The basic location is on the right side of the barrel under the operating rod. (Just pull back the op rod to lock it open and look at the recess in the stock, you should see the barrel info stamped there.)
Early NM barrels had a diamond stamped with the other info there.

(Some markings may also be located under the handguard on the top of the barrel.)
As far as the gas cylinder and lock screws, you might want to check at FultonArmory.com There are too many types and markings for lock screws to remember and a few types of gas cylinders also.

I hope this helps some.... oh yea, whatch out for "Garand Thumb"

thanks for the welcoming! here are all the places i have looked so far. The only place i havent looked and im not sure if i have the skill to look is under the wood. Is it easy and worth it to take the wood off to look? i have included the photos of the hunt as an attachment

I believe that early 1951 contract Marlin barrels had no markings on the side. They were marked on top with an "M" and 6535448-MARLIN-
As far as I know all other US barrels had at least the date and "P" proof on the side. I may be wrong about this an is so, hopefully someone will correct me. It could also be a commercial barrel.

You can remove the hand guards. It is not hard but if you have never done it, getting the rear hand guard back on can be tricky. But if you don't try it you will never get the hang of it. Give it a try, just be careful and if you have a problem ask for help from forum members. Good luck.

Original Marlin barrels were used during WW2, very rare. Post war barrels will have a 51 or 52 stamped on the side where you would find the date and SA on Springfield barrels.
I have seen only two WW2 Marlin original barrels on Springfield Garands. One was an original all correct 1943 Springfield Garand (Sold to a friend). The other I still have, not 100% correct but with parts from Aug. 42 date of manufacture.

Welcome, but be careful about offering advice here unless you're sure. Neither of these is factual.

I suspect this barrel may just be a civilian manufacture replacement. Enough guns came back from other places with shot out pipes so...the demand was there.
