Bolt and oprod are correct for mid-50's production. The bolt heat code (A15) is for serial numbers 5,42X,XXX to 5,96X,XXX , so it could be the original bolt, but is certainly correct. Pics would help with the rest of the rifle. |

Most Garand parts are marked with a "Drawing" number. WW2 Garands are marked "D" and "C". These indicate the size of the drawings. There are actualy drawings numbers "B" and "A", but the parts are too small to have numbers stamped on them. Post war numbers will have the same numbers but the letters are chanbed to numbers. ie. "D" = 65, and "C" = 55.
For example, a WW2 receiver will be marked with a D28291, plus the makers initials. Post war receivers will be marked D6528291. Receivers are treated a little different than other parts. They will also have a heat lot code stamped on them, as well as a revision number. A revsion(update) number is specific to a certain serial number range. Post war receivers often do not have revision numbers, and may or may not have a heat lot code. For example, a WW2 receiver with a serial number of 1.9 million to 2.3 million will have D28291 30 stamped on it. The "30" being the revision number. Early Garand receivers often have an interesting modification done to them. Many receivers SA and Win will show a very dark color to the heel. This is the result of dipping the receivers in molten lead to anneal them to prevent cracking. It was done to many receivers prior to ambout Sept - Oct 1943. The change in the metalurgy resulted in a color change when the receiver was parkerized. These receivers are often referred to as "Lead dipped". Kind of a unique two toned color on the receiver. Some times it stands out, and sometimes it is hard to see. Op rods are similar. WW2 op rods have a number like D35382-6-SA stamped on it. The "6" being the revision number, and the "SA" being the maker's initials, Post war op rods will be marked D6535389 or 6535389. Op rods also have another interesting feature. WW2 op rods will be described as "cut" and "uncut". The cut referring to a stress relief modification done at the square joint weld to prevent cracking. Post war op rods are all cut at the factory, and will have a larger diameter cut (5/16") as opposed to modified op rods which have a 3/16" cut. Earlier made op rods may have a curved or flat side, and also an angled front. Bolts will be marked in a similar way. Uisng a Garand I have as an example, it is a 1.95 million reciever. For that range, it should have a D35389 6 SA(Straight front, concave curve, un cut op rod), as well as a S28287-12SA bolt. Your receiver and parts look like they are pretty much origianal and proper. All Garand parts are made to be interchangable, so that any numbered part could end up on a gun during rebuild. |
