I have just read your very fine article about the Modelo 1909 Mauser
Cavalry carbine, and found it very good indeed. I own also a Modelo 1909
Mauser carbine, but not the cavalry type you have but the Engineer's type,
that has the same barrel dimensions as the cavalry type but the stock is
different, very similar to the Kar98 used by Germany during WW II. It has
a turned down bolt handle, like the cavalry model and unlike the infantry
rifle, which has a straight bolt handle.
Regarding what you said about the barrel being counter bored at the
muzzle, it might not be a counter boring but a bushing welded at the muzzle
to allow the use of a bayonet, which was a modification made on these German
carbines and on some of the first ones of those made in Argentina in the
Domingo Matheu factory in the city of Rosario, between 1947 and 1962. The
later ones made in Rosario had a barrel 1/2 an inch longer instead of the
In brief, the Mauser Modelo Argentino 1909 came in three types:
1) Infantry rifle, of 49.21 inches total length and 29 inches
barrel length, straight bolt handle, with a four digit serial number preceded
by one of the following letters: A, B, C, D, E, F, G, H, I, J, K, L, M,
N, O, P, R, making a total of 180,000 rifles.
2) Engineer's carbine, with a total length of 41.89 inches and
a barrel length of 21.89 inches, a turned down bolt handle, with a four
digit serial number preceded by the letter A only, making a total of 10,000
3) Cavalry carbine, like the one you own, total length of 41.57
inches an a barrel length of 21.89 inches, a turned down bolt handle, with
a four digit serial number preceded by the letters A, B and C, making a
total of 30,000 cavalry carbines.
All of these were manufactured in Germany by DWM, and the quality of
manufacture is like the one you have described, which makes them a very
sought after item. Prices here in Argentina vary from 300 to 350 US dollars
in the military surplus stores for conditions good to average.
The cavalry carbine was also manufactured in Argentina, as you said,
in the Fabrica Militar de Armas Portatiles (F.M.A.P.) (Light Weapons Military
Factory) Domingo Matheu, belonging to the Direccion General de Fabricaciones
Militares ( D.G.F.M.) (General Directorship of Military Factories) from
1947 to 1962. These had a six digit serial number, without letters, from
000,001 to 019,989, but some of the intermediate numbers were not used,
the approximate number manufactured was 19,800.
The markings on these argentine carbines is of two types:
a) EJERCITO ARGENTINO
MAUSER MOD 1909
b) F. M. A. P.
MAUSER MOD 1909
DIRECCION GENERAL DE
The Domingo Matheu factory also made, under licence from the Colt company,
an argentine model 1911-A1, in .45 ACP which is also of very good quality.
The approximate number manufactured was 80,000.
Other weapons in production under FN licence are the FN-FAL rifle in
7.62x51 (NATO) caliber and the Browning HP39 semiautomatic pistol in 9mm
I hope this info from Argentina will be of interest to all the gun buffs
that visit your very fine web-site, please let me know if you find it so.
Best regards and keep up the good work.
