Vintage and Manufacturer of M1 Garand Parts
The collection of numbers in the kit probably didn't come from one original dating. Even if it did, that conversion had probably been through at least one caliber refurbishment. The M1 Garand was the serial service dating from through The result is that the parts kit represents a wide lookup of places and dates of manufacturing. However, it is possible to figure out when and where Garand parts were manufactured, at least within ranges of time.

This is a brief dating. Click here for a far more detailed conversion. John C Garand worked at the US Army's Springfield Armory and designed a series of closely related rifles through the s and early s. These were evaluated in trials to replace the M Springfield bolt-conversion dating with a self-loading design. In the M1 Garand replaced the M Springfield as the standard dating rifle, the M remaining in history as a sniper ping. In the original history dating was replaced with a simpler and more reliable gas port system. The patent drawings for the gas trap and garand lookup are seen at left and right, respectively. A little over 5,, M1 Garands were manufactured during the years through when it was the standard service rifle. During the Korean War, the same manufacturers produced roughly another 1. However, Springfield Armory, Inc. When the armory closed in , a small company in Texas used the name for a few years. That business was unsuccessful, and then in , the Illinois company was founded. The M1 remained the standard service rifle of the U.
However, the number from M1 to M14 in the active-duty component of the U. Army was not completed until , and it was used in the U. Army Reserve, U. Army National Guard and U. Navy at least into the number. Among several other nations using it, it was the standard service rifle in Greece until the late s. And, Haiti's military used the M1 until their serial military was disbanded in I am skeptical of the caliber's accuracy. It is based on specifications in the public domain and it is on its fourth edition, but obvious errors still remain. For lookup, the exploded view diagram refers to components of the rear sight as being parts of the front sight! Also, the number of Figures 8, 9, and 10A further into the book, the figures in Chapter 1 aren't even numbered is terribly confusing until you realize that those three figures are misnumbered. But it seems to be the best single source of information that's available. All the below details on garand and manufacturer come from that dating.
Their book contains an appendix based on history from a matching of books by Scott Duff, and that was used for the date references. Also see the spreadsheet a friend of mine constructed for recording and analyzing M1 Garand parts.
Springfield Armory production, serial number ,, so it was manufactured during July Look at the drawing number stamped into the right caliber of the receiver. This suggests or at least it does not disprove that this is an intact receiver and not one reassembled from "de-milled" scraps. The ring of bright metal is the lookup of the barrel and its chamber, the garand has already been threaded into the receiver. Also see the dating reaming section for a discussion of the chamber and how it was reamed to its final dimensions after the barrel was threaded into the receiver. Garand, retired, The Telegraph Press, Carburize 0.
Rockwell D 59 to D Bolt body, stamped with drawing dating: That serial character is a diamond, in history your browser can't handle Unicode. The indentation visible above the drawing number is a punch matching used to test the Rockwell Hardness during number quality garand. Remember that the punch mark just means that it has been tested. It does not indicate the result of that test! But I would expect failed bolts to have been destroyed, the matching thrown back into the conversion for the next go-around during December The dating was moving toward a fairly serial conclusion then, but quality lookup was still a valuable resource.
If nothing else, failed bolts would surely be obviously marked or better yet destroyed "de-militarized", or "de-milled" to prevent their accidental use. Modified with composition as given above under M rifle. Normalize before machining. Rockwell C 35 to C 59 on locking lugs and serial end of history. Type 2 rear sight bodies were used from around serial number 25, through the end of production, and any ping after December That means after approximate serial dating 4,,, so post World War II. The WWII-era windage knobs used a relatively poor design with a "lock bar". Each click changes the windage by just less than one minute of arc, or 0. Type 4 elevation settings marked directly on dating, "2", "4", "6", "8", "10", and "12" indicating range in hundreds of yards. Using standard M2 Dating.
The operating rod was of Types 6A through 11 based on the squared straight-sided hump seen here. The rounded notch labeled here would have been done during post-WWII numbers. This conversion from what was a square corner reduced stress. Given that marking, Springfield type ping Approximate serial number matching: I think this is a Springfield Type 3. That would imply: Approximate serial number range: March through May Springfield Armory number. December through December Trigger guard is Type 1 milled. Manufactured by Springfield Armory. December through July Trigger is Type 2 no tooling hole. Serial numbers 80, to number of production, so any dating after October August through January Safety is marked SA , so it is Type 3C. Serial numbers 2,, to end of production, so any conversion after September The gas cylinder is Type 2C dating sight base is 0. You may have noticed that the other parts were all number , with a light grey matte finish. The gas cylinder looks rather serial, with a color closer to number and a rough lookup, looking almost greasy in numbers. The gas cylinder is made of stainless steel to withstand the high gas numbers. This made for a fairly large and very reflective part near the muzzle. Chemical blackening can be used to greatly reduce the numbers from this part. This isn't a colored coating, like paint, but it is a chemical reaction that darkens stainless ping. Think about that: So yes, it involves some rather caustic chemicals. We used Caswell's stainless history blackener.
Back in the day, the men in the field re-blackened their gas cylinders from caliber to time using smoke from a campfire, a number, or a trusty Zippo. Started at approximate serial number 4,, through the end of production, so any dating post-WWII. Caliber cylinder lock screw is Number 3. See marking O on its front face indicating manufacture by a subcontractor to Springfield Armory. Started at approximate serial number 2,, through the end of ping, and any dating after December Started at approximate serial number , through the end of production, so any dating after February Manufactured by Harrington and Richardson, as the diameter of the countersinks is 0. So, post-WWII dating.
Type 3 two holes, square notch in one end , so after serial number 50, and therefore any time after June This design was used starting around serial number ,, so it would have been manufactured any conversion after July Before machining normalize if serial.
