Mis-matched A rifle with one or more of the threesecondary serialed parts (bolt, floorplate, or buttplate) numbered differently than thebarrel.

Finn matched A Finnish built or marked rifle thathas had the bolt renumbered to match the barrel. Although buttplate and floorplatenumbers may or may not match it would still be considered Finn matched. A rifle witha mis-matched number on the bolt body, but the last few digits of the barrel number on thebolt knob would still be considered Finn matched.

Electropenciled A method of etching parts with aserial number which was often used during refurbishment.

Alpha prefix The letters preceding the serialnumbers on Soviet and Eastern European Mosin Nagants. They represent a block of 9,999rifles and were apparently assigned at random.

Westinghouse Serial Number Age

1	Primary serial numbers on Mosin Nagant rifles, like most European firearms, are on the barrel, rather than the receiver as in the United States.
2	Secondary serial numbers are found in three other locations on the majority of Mosin Nagants. Bolt
3	Magazine floorplate
4	Buttplate
5	Cocking knobs were also numbered on the earliest Russian production and Remington M91s. Numbered cocking knobs are uncommon now and it is rare to find one that matches. They are most often encountered on rifles built in Finland from salvaged parts.
6	Stocks are occasionally numbered. M91s from the Balkans (seldom matching)
7	Later Soviet production such as M38s, M44s, and M91/59s which were probably numbered during refurbishment
8	Soviet replacement stocks in pencil in the barrel channel
9	Soviet postwar M44 stocks stamped under the buttplate
10	Late Chinese T53s instead of the buttplate
11	Bayonets are also numbered at the base of the shaft
12	Cleaning rods are not typically numbered but here is a case where one is. It is not matched to the rifle and it is possible that it is not a serial number, but represents something else.
13	Chatellerault prefixed the number with an 'N' which stands for 'number' and is not a letter found in the Cyrillic alphabet. It is technically not a part of the serial number although it is usually included in the serial number by US importers and FFL holders for record keeping purposes. Production started at serial number 1 and ran straight through to the end of the contract.
14	Here is a renumbered bolt that has the 'N' prefix on it. Since the 'N' was not part of the serial number it is usually not found on the numbered parts other than the barrel. This was probably done in a country other than Russia where the meaning of the 'N' was not recognized.
15	Tula used the same 'N' prefix until 1928 when the barrel markings changed. Each year started over at serial number 1.
16	Tula began to use 'No' above the serial number when the barrel markings changed in 1928. This also stands for 'number' just as the 'N'.
17	Izhevsk did not use the 'N' prefix or the 'No' symbol. Each year started over at serial number 1.
18	Sestroryetsk used 'No.' above the serial number, which means 'number' just as the 'N'. Each year started over at serial number 1.
19	New England Westinghouse used 'No.' above the serial number, which means 'number' just as the 'N'. Production started at serial number 1 and ran straight through to the end of the contract.
20	Remington used 'No.' above the serial number, which means 'number' just as the 'N'. Each year started over at serial number 1.
21	Serial numbers repeated at the Russian/Soviet arsenals and at Remington each year as seen on this rifle and the one following. 1932 Tula M91/30, serial number 94015.
22	1935 Tula M91/30, serial number 94015.
23	Letter suffixes follow some serial numbers. These are typically found on M91s from the Balkans and are thought to have been added by other countries. They are not part of the original numbers. Letters which have been observed are 'G' (possibly Turkey).
24	'E'
