A question for the Springfield experts.
About 10 years ago, my father-in-law decided it was time to distribute his guns to his kids. He gave his daughter (my wife) the 03A3 that he had purchased thru the NRA back in the 1950's. He wanted it to have as a spare in deer camp and it has remained unmodified. He told me that it was tagged "unserviceable" but appeared un-fired. He told me that when he got it, he fired it less than 10 times just to make sure everything worked.
I have been shooting it in the military benchrest postal matches, and did an accuracy test with several different vintages of GI ammo. Needless to say, I have shot it a lot more than he ever did.
I pulled the stock off this afternoon because I wanted to check a couple rust spots on the barrel. I had found these spots and cleaned them up right after I got the gun.
The rifle is a Remington, serial is 3879XXX, and it has a 2 groove barrel. The visible markings on the barrel are 7-43 an ordinance bomb, and RA behind the front sight. The wrist of the stock on the left side is stamped RA, an ordinance bomb, and FJA in a rectangle.
Now my question. When I got the stock off, I started noticing all of the stampings that were under the wood, both on the barrel and the receiver. Is there any publication that explains what the stampings are?
