M1 Garand Stock Identification Guide


The 4 original manfacturers of M1 Garand stocks were:
Springfield Armory
Winchester Repeating Arms
Overton Woodworking Corp. (for International Harvester)
Harrington and Richardson Arms Co.

The differences between the stocks are in the curves of the pitol grip area, and the "Horseshoe" area on the top of the stock where the back of the receiver sets.
This picture shows the first 2 shapes of stocks used by Springfield Armory and Winchester.
The upper stock has a shorter-radius curve going from the bottom of the pistol grip to the back of the floorplate area. It was used by Springfield from serial number 1 until about serial number 75,000.
It was also used by Winchester from serial number 165,000 to the end of production. The arch was less rounded at the beginning of use, and was more rounded as in this picture by serial number 1,210,000.

The lower stock has a flatter arch, and was used by Winchester from serial number 100,000 to about 165,000.
It was also used by Sprinfield Armory from serial number 75,000 to 3,850,000 (end of WW2 production).

This shows the Horseshoe area. The SA has a Small Horseshoe, and the WRA has a Large Horseshoe. Winchesters can have Large or Small Horseshoes.

Springfield Armory left, Later Winchester right.
The SA has a "U" shaped notch for the bottom of the triggerguard.
It was also used by Wichester from 100,000 to about 165,000.
The Winchester has a "V" shaped notch for the triggerguard starting at about serial number 165,000.

3 Winchester stocks with "V" notches.

Front of Winchester stock. Most have a 2 or 3 digit number, and some a letter stamped here. This stock has "229" on it. This may have been a lot or batch number the stock was part of.

A Winchester stock should have 3 characteristics:
1. A "V" notch.
2. More rounded pistol grip area.
3. Number and maybe letter stamped on the ferrule.


Barrel Channel Varieties: Long barrel channel, 2 1/8", WRA.
Short barrel channel, 1 5/8", SA.

The long barrel channel was used from SA serial number 1 to about serial number 520,000.
The short barrel channel was used from about SA 520,000 to the end of production.

The long barrel channel was used from WRA serial number 100,001 to about serial number 2,350,000.
The short barrel channel was used from about WRA 2,350,000 to the end of production.

Another difference between SA and WRA is the end of the operating rod cut. The SA has a straight diagonal cut (to the right of the SA in the white box), and the WRA has a curved cut.

The change was made to prevent the operating rod from rubbing on the stock.
WRA long channel.

Horseshoe area differences on Post 1945 stocks.
IHC notch, and some Winchesters also had a notch on the right side.
Pistol grip area differences on Post 1945 stocks.

After WW2 ended, the Overton Woodworking Corp. of Chicago began making replacement M1 Garand and Carbine stocks. One of their machine setups created a triggerguard notch similar to the Winchester "V" notch. Some sellers of these stocks optimistically describe them as Winchester stocks, when they are not. This picture shows a Winchester stock on the left with the full "V", and an Overton stock on the right with a semi "V".
The Winchester stock is on the top, with the more rounded pistol grip curve. The Overton stock is on the bottom, and has a less rounded curve. Overton made these stocks in both walnut and birch. This one is birch, made after 1960.
The Ebay seller described it as a WW2 Winchester stock.

Walnut stocks were used in the manufacture of M1 Garands.
Birch stocks were made AFTER rifle production ended in 1957.
Walnut is browner, birch is yellower.
