Types of Markings

Date(s) Country of origin Manufacturer name Serial number(s) Proof mark(s) Unit number Import marking

Patent marking Model name/number Brand name Military acceptance Refurbish mark Conversion marking Caliber

3

Where was this rifle made?

4

France – the markings translate to:

Ordnance

Factory

Chatellerault

Chatellerault was a major French state arsenal

5

Two More

What is the point of showing these examples?

Context is essential!

Always consider the whole gun to understand what you are looking at.

7

Proof Marks

What is a proof mark?

8

Why Proof Marks?

(in no particular order) Public safety

Industry reputation Government oversight

9

Proof Loads

Typically 25% - 30% overpressure Either one or two rounds

10

Proof Marks - England

The modern British proof law was passed in 1868, with an official nitro proof added in 1904 and a general update in 1925.

British law did not automatically recognize foreign proofs, so many arms imported into England had to be re-proofed.

Up to WWII, pressure was measured in tons.

11


Birmingham proof mark used prior to 1904:

Indicates black powder proof unless accompanied by the words “Nitro Proofed”

12


Standard proof marks, 1925-1954:

Birmingham London

Final proof

View proof

Nitro proof

13


Standard nitro proof marks, post-1954:

Birmingham

London (on action)

(on barrel)

14


When on foreign-made guns, the proof marks were enclosed in a circle, and accompanied by the mark “NOT ENGLISH MADE”:

15


In addition to everything else, a special mark was used to date the proofing.

From 1922/23 to 1940/41, this mark was used:

A=21/22, B=22/23, C=23/24, etc.

I and Q not used.

From 1950 to 1974, it was this one:

A=1951, B=1952, C=1953, etc.

I not used (but Q was).

16


Lee-Enfield No.5 rifle, rebarreled in 1974

17

Proof Marks - Belgium

Royal decree in 1672 required proof testing and marking of barrels

Belgian national proof house established in Liege In 1888, a new law forbade the sale or display of

unproofed firearms In 1891, proof testing standards for smokeless

powder were introduced

18


Crown over R – Black powder proof of a barrel (also appears on smokeless barrels).

“Perron” - Indicates fit and function of slides, locking mechanisms. Used from 1903 to 1924 (not on revolvers).

Rampant Lion “PV” - used 1898 - 1924 for smokeless barrel proof. After 1924, it replaced the Perron mark entirely.

19


EPV (Epreuve de Liege) with crown – final overall proof mark after 1893

Plain EPV – final overall proof from 1853-1893 (used on muzzleloaders after 1893)

Star over letter – Individual inspector's marking, 1877 to present. From 1853 to 1877, a crown replaced the star.

20


Black powder, post-1893

21

Proof Marks - Germany

The modern German proof mark law took effect in 1893, and remained definitive until 1939.

In 1939, the proof marking symbol was changed form an imperial crown to a Nazi eagle.

The well-known Waffenamt Nazi symbol was actually a military acceptance mark, and not a proof mark.

22


1891 – 1939 proof marks:

Nitro Black powder Choked bore

Final proof Rifled bore Smooth bore

23


Weapons manufactured prior to the proof law taking effect (1893) were required grandfathered, but had to be marked (this did not constitute an actual proofing).

24


In 1939, the crown was replaced by an eagle, and the typical 3-proof combination (B, U, and G) was replaced by a single eagle/N mark.

25


Typical commercial Mauser rifle

26

Proof Marks - Italy

Italian replica cowboy pistols are probably the most likely place to find black powder proofs today.

Italy has a nice simple set of proof marks, but a rather strange date code system.

27

Proof Marks - Italy

The proof marks:

Black powder proof

Smokeless proof

Final definitive proof

Brescia provisional proof

Gardone provisional proof

28

Proof Marks - Italy

29

Proof Marks - Italy

Proof marks on an Uberti 1858 Remington copy:

Proofs will also be found on barrel and cylinder.

30

Proof Marks - Spain

Eibar proof house established in 1844, proofing made mandatory in 1923.

Typically appear as a set of 3 markings:

31

Proof Marks - Spain

First mark is the actual final proof – gun is good

Early (1923-1928) Late (1928+)

Second is the date Until 1927/28, a “P.V.” A – 1927 was used instead of

B – 1928 the date

C – 1929...

32

Proof Marks - Spain

Third mark is an admission to the proof house:

Early (until mid 1931) Late (mid 1931 – now)

(The King fled in 1931, and the crown went with him)

33

Proof Marks - Spain

With this in mind, we can interpret this typical Spanish set of markings:

Gun was accepted and proofed in 1945

34

Other Markings

Date (of manufacture or refurbish) Model name/number Manufacturer name

Import marks Serial number(s)

Caliber Military acceptance

35

Date(s)

Dates marked on a firearm can mean several different things:

Date of manufacture Date the gun was refurbished

Date the model was adopted for military use Date the design was patented

36

Date of Manufacture

Dates can take several forms -

37

Manufacture Date

38

Refurbish Date

Sometimes a firearm is marked with the date of a major repair or conversion:

39

Refurbish Date

40

Refurbish Date

41

Adoption Date

Model dates are usually more obvious...

42

Adoption Date

...but not always.

43

Model Name/Number

Probably the most unambiguous type of marking...

44

Model Name/Number

But what if you can't read it?

(Iranian Mauser)

45

Model Name/Number

This very clearly says that it is a Type 99

46

Model Name/Number

Store brand guns – this was actually made by FN

47

Manufacturer Name

On civilian guns, typically company name On military guns, typically arsenal name

Sometimes just a location

48

Manufacturer Name

Often a company's location will also be marked – this was how you could find the company.

49

Country of Origin

This is rarely directly marked on military arms, with the exception of guns imported for commercial sale

It usually must be inferred from other markings

50

Import Markings

In 1968, the GCA required this information to be marked on all guns imported into the US:

Serial number Manufacturer Country of origin Model designation Caliber Importer name Importer location (city & state)

51

Import Markings

Typically abbreviated heavily:

Century International Arms, Saint Albans, Vermont

52

Import Markings

Location varies – 2002 regulation change required them to be “conspicuous”

Serial number may not contain non-latin numbers – if it does, a new one must be marked.

53

Import Markings

Possible locations Under front of barrel Under grip panels (old) Side of receiver Sometimes tiny!

54

Import Markings

Prior to 1968, commercial imports had to be marked with the country of origin

55

Import Markings

Of course, they sometimes goofed...

56

Import Markings

Remember, not all info has to be in the same place.

If the caliber, model, or other data is already on the gun, it does not need to be marked again.

Import markings are not required to be on the receiver, but are illegal to alter or deface. However, it is legal to remove parts they are on (ie, barrels) for repair.

57

Serial Number

In the US, serial numbers became legally required on guns in 1968.

Virtually all military arms have serial numbers.

Most pre-1968 commercial arms of reasonable quality and cost also had them.

58

Serial Number

Often multiple large parts are

serial numbered.

On commercial arms, it is rare

for parts to be mis-matched.

On military arms, it is fairly common – usually bolts

59

Serial Number

Some folks (like Germans) would serial number everything right down to the screws:

60

Serial Number

The only legally required serial number is the one on the receiver – but this may not be where a manufacturer marks it:

61

Serial Number

Sometimes military arms will have unit markings, which look like additional serial numbers:

62

Serial Number

Foreign-made guns may have numbers printed in non-Latin numerals:

Looks like “AK”, but it's actually “DK” in Cyrillic

63

Serial Number

Arabic script...

64

Serial Number

or Thai script...

65

Serial Number

Letters within a serial number... Production block code (very common) Date code (fairly common) Prefix meaning “number” (“N” on some rifles) Suffix meaning “year” (cyrillic “r”) Model or feature designation (often built into the

serial number rather than separate)

66

Caliber

Generally caliber markings on military arms specify the bore diameter only – the specific cartridge must be determined from context.

67

Caliber

Which 9mm, exactly? Spanish JoLoAr:

9x17mm (.380ACP) 9x23mm (9mm Largo)

68

Caliber

Military forces often updated guns to different cartridges, and did not always mark them clearly.

69

Caliber

It was also fairly common to change the chamber profile to accept different bullet profiles.

70

Caliber

Overall length can be a good clue to caliber changes

71

Caliber

Common opportunities for pistol caliber mixups: 7.65mm Browning (.32 ACP) vs 7.65mm Luger

(7.65mm Parabellum) 9mm Kurz (.380ACP/9x17) vs 9mm Parabellum vs

9mm Largo (9x23mm) vs 9mm Browning (9x20SR)

The really confusing one is 9mm Largo vs 9mm Bergmann-Bayard vs 9mm Steyr, as they are all 9x23mm cases.

72

Caliber

Occasionally, militaries actually try to be helpful:

73

Military Acceptance

Many models of firearm were made for both military and commercial sale. Military acceptance marks can help determine the provenance of a particular gun.

74

Military Acceptance

A few examples...

Austria

Switzerland Israel United Kingdom

France US Nazi Germany

75

Military Acceptance

One special case worth mentioning is the British “DP” mark, for Drill Purpose

Generally meant the part was out of spec, and not to be used for live fire.

76

How about some strange and goofy markings?
