Did you ever wonder what that little disk in the stock of your Swedish Mauser meant? Or maybe the disk is missing and you wanted to know what that hole in the stock was all about. Suzie’s here to solve the mystery for you.
The Swedish military added a small cut in the stock of their rifles to accommodate a disk that was a little over an inch in diameter. Two overall types of disks were used and provided slightly different information to the user.
The first design was used prior to 1941 and the adoption of the m94/41 cartridge and was used as a means of identifying the unit to which the rifle belonged. Made of brass, aluminum, and zinc, the disk was marked with the branch of service, the unit or regiment number, and the rack number. The rack number refers to the slot of the rack on which the rifle was stored during inventory. The disk was placed on the stock so as to orient the lettering parallel with the butt plate. Branches of service were indicated by initials.
The early disks carry a number of variations in style depending on the regiment, division, or unit and can be hard to decipher. The table below is not comprehensive, but instead, gives a few of the major markings found.
|Klg fl||Kungliga flottan||Royal Fleet|
|MDO||Ostkustens Marindistrikt||Eastern Naval District|
|MDS||Sydkustens Marindistrikt||Southern Naval District|
|MDN||Norrlandskustens Marindistrikt||Northern Naval District|
|MDV||Vastkudtens Marindistrikt||Western Naval District|
|SK||Stockholms Kustartilleriforsvar||Stockholm coastal artillery|
|BK||Blekinges Kustartilleriforsvar||Blekinge coastal artillery|
|GK||Gotlands Kustartilleriforsvar||Gotland coastal artillery|

|HK||Hemo Kustartilleriforsvar||Hemos coastal artillery|

The second design has two variations. Both were used after the adoption of the new cartridge in 1941 and were divided into three sections. The largest of the three sections in either pertains to the barrel at the throat of the chamber. Measurements were taken at the throat to check for erosion.
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.
A few carbines may have one of two other types of disks. Some were sold to Denmark after WWII and will have a Danish coin in place of the original disk. And in 1950, carbines imported by InterArms Company will have a disk reading ” Cal. 6.5mm Swedish” at the top and “Made in Sweden” at the bottom.
Now when your friends ask you about that little piece of metal in the stock of your Swedish Mauser, you can tell them a little bit about the history of the rifle. Go show off!
