Understanding Swedish Mauser Stock Disc Markings
 



Three examples explained below:








Section I in the first variation’s exterior row of numbers reads 2 through 5 and the interior row contains 9, 0, and 1. The exterior is assumed to begin 6.51 and the interior 6.48. To read these disks just replace the last digit (1 or 8 ) with the marked digit, with zero standing for 10 and 1 standing as 11. So a first variation disk marked on the 9 has a 6.49mm bore and one marked 1 is 6.51mm bore. When the barrel erosion reached 6.55mm, it was decommissioned and replaced.

The second variation is similar, but accounted for a minimum acceptable diameter of 6.46mm. The exterior row is marked 6.51 followed by 2 through 9 and the interior contains 6.4 followed by 7-9 and a 0. An arrow over a particular number substitutes for the 1. For instance, a disk with 6.51 and an arrow over the 6 would indicate a diameter of 6.56. When the diameter reached 6.59, it was replaced.

Section II contains numbers 0-3 and referred to the condition of the bore. 0 would indicate a bore with no rust, abrasions, or corrosion. 1- Minimal darkening in areas. 2- Some rust or corrosion along the borders of the lands and grooves or within the grooves themselves. 3- Rust throughout, but without sharply defined edges. 4- Significant rust with sharply defined edges or corrosion throughout. When the bore reached an evaluation of 4, it was replaced and is therefor not listed on the disk.

Section III indicated the hold over the shooter must apply to the rifle. This applied to rifles sighted for the original 94 cartridge and was meant as an adjustment when using the newer m94/41 cartridge. The disk has three markings. “Torped” meaning “spitzer” which refers to the new 140 grain count spitzer round that was in use. “Ӧverslag” meaning the “impact above.” And “Str” which was the abbreviation for “streck” or “point” and indicates how many decimeters (or 10 cm) over or under the shooter would have held at 100 meters. In 360 degrees, there are 6,300 streck, so each meant an adjustment of 1 decimeter for every 100 meters. This section was not always marked, however.

Just how did the US Government become involved in purchasing the .303 British No4 Mk1* rifle? 

"Many in the US Military and US Government knew that sooner or later the US would be dragged into the war. They especially wanted the UK to remain free of the Nazi control that had settled across the continent of Europe. US Forces would need a base to operate from when it came time to launch an invasion of Western Europe. The British Isles were a perfect jumping off spot. The short trip across the English Channel would keep troops fresh for the battle that lay ahead. However, the US was not at war with either Germany or Japan at this point. Since the United States was officially “neutral”, the Neutrality Act of 1939 forbade “direct involvement” in the war; our allies were technically on their own. How could we help, but not violate the law?
Crafty politicians & lawyers in Washington read the law extensively, and wrote a bill to give the president the power to put the vast industrial base of the US at the disposal of our allies, but not have to declare war, or have war declared on us by the axis. Thus, the LEND LEASE ACT OF 1941 came into being. Because the war material supplied was “officially” US PROPERTY, and so marked, it managed to squeak past the benchmark of an outright violation of neutrality. Thus, the US managed to keep our allies supplied with war material, yet, still remain on the correct side of US and international law (though just barely).

So it was that Savage Arms Corporation in Massachusetts got a contract to produce Lee-Enfield No. 4 Mk I* rifles. Savage produced over 1 million No 4 Mk I* rifles between 07/22/41 and 06/22/44. The exact number is in dispute, however, all sources do agree the total was far in excess of 1 million."

In USGI lexicon, MRT means Mildew Resistant Treated. 

USGI canvas and leather field gear would be cleaned and refurbished prior to storage for re-issue.  In the late 1950's a Mildew Resistant Treatment began to be applied and items were ink stamped MRT and the year of treatment.

From 1916 through 1955 these holsters were Tan leather.  In 1956 the US Quartermaster Corp determined that all leather goods should be dyed black.  This resulted in both new production items being delivered in a black dyed finish as well as older pre-1956 leather gear that was inspected for wear and tear and then dyed black. 

Early black M 1916 holsters (ca 1960s) were correctly made of good leather. The older black holsters may have a greater collector's value, due to their Vietnam era connection. But W.W II vintage holsters were used there as well in both Tan and Black finish. The Recent black production holsters seem to use a thinner leather and do not age as well as the earlier examples.

In our opinion, the collectible '' hierarchy '' would be :

- pre-W.W II tan,
- W.W II tan,
- tan dyed black,
- early original black,
- recent black

 Scrapping Firearms

This question comes up from time to time on how to legally scrap a firearm.  This pertains to FFL holders (01, 03, etc). 


"The regulations in 27 CFR 178.122, 178.123 and 178.125 require each licensed importer, licensed manufacturer, and licensed dealer, respectively, to maintain such records of acquisition (including by manufacture) or disposition, whether temporary or permanent, of firearms as therein prescribed.
Held, a licensee who purchases a damaged firearm for the purpose of salvaging parts therefrom shall enter receipt of the firearm in his firearms acquisition and disposition record. If the frame or receiver of the firearm is damaged to the extent that it cannot be repaired, or if the licensee does not desire to repair the frame or receiver, he may destroy it and show the disposition of the firearm in his records as having been destroyed. Before a firearm may be considered destroyed, it must be cut, severed or mangled in such manner as to render the firearm completely inoperative and such that it cannot be restored to an operative condition."


It is our recommendation that in the destructive process, the portion containing the serial number should be retained as physical proof of the scrapped receiver/frame.  This piece should be small enough that storage issues would not apply.
