Jack J - not sure what “leads” you are looking for on the Factory
at Santa Fe, near the Federal District of Mexico (Mexico City). I
have found very little. There is some information in the book
"Mexican Military Arms, the Cartridge Period 1866-1967", by
James B. Huges Jr, Pages 120-121. Because of a general lack of
backup material, I can only quote the book, but cannot guarantee the
accuracy of the information. I will quote it, as I don’t have time to retype
the two pages of text on the referenced pages.
“On the 7th of May, 1900, the brother of Gral. (note: General) Manual
Mondragon, Lt. Col. Enrique Mondragon, opened the National Powder
Factory extension at Santa Fe, near Mexico city.”
“In 1906, as a part of a military industry expansion program begun by President
Porfirio Diaz in 1897, the Santa Fe extension was enlarged to include an
Artillery Park, a National Arsenal, and an Artillery Foundry. This same year, the
small arms ammunition plant, Fabrica Nacional de Cartuchos, was opened to
produce 7 mm Mauser cartridges for the rifles and machine guns then in service.
This plant was patterned after those in New Haven, Bridgeport, and Karlsruhe.
With the introduction of the then new Naval Yard and Arsenal at Ulua Castle in
Verz Cruz harbor this same year, the importation of cartridges ended. All other
arms and war material was still imported.”
Note: The earliest FNC date I have seen or heard of on a 7 x 57 mm Mauser cartridge
is 1909. This does not address a factory using the headstamp FNA (Fabrica Nacional
de Armas) that made at least blanks, reported in .43 Spanish and .50 Carbine calibers,
with headstamps dated in 1886, as well as a .30-06 proof load, date unknown, with
headstamp FNA Sobre Presion.
“1963 saw a new building for the National Munitions Factory inaugurated in Tecamachalco
as well as the explosives plant in Santa Fe. Production for the year 1963, by the Military
Industry Department for the army and navy amounted to 25 million pesos.”
“The Government of Mexico is keeping the military production facilities current.”
Not really much information there. No explanation of the changes in nomenclature for
the cartridge division of these factories (FNA, FNC, F de M, F de C, FC) that appear
or did appear a various times, or the headstamps of Mexican cartridges all believed to
be made at the Government factories. We are not including purely commercial operations
here, even if they made some ammo for the Mexican Military.
Hope this is of some help. Wish I had more.
