Part 3.

In the book " Cartridge for Collectors " Fred A. Datig presents two curious information, the first one is the existence of a 7,65x53,5mm Marga, developed at the beginning of the 20th century by the Belgian Captain Uldarique Marga for a rifle and machine gun of his invention. It have an almost identical case as ours 7,65 but with a small rim. The other one, the 7,65x61mm Argentine Navy Match that seemingly was developed by Winchester for the shootingteam of the Marina Argentina (argentine Navy) in 1914 taking as a base the case of .30-06 Spr. to be used in the 1916 Pan-American competitions. A limited series of this cartridge was done to commemorate 40 years of the Association collectors' Argentina of Weapon and Ammunitions (AACAM) in 2006.
To finish I would like to add last two really curious anecdotes in connection to our 7,65mm. The first one is the appearance of 7x54mm ammunition in the South of Africa during the War of the Boers. These cartridges were used in guns Mausers 7x57mm in the same way as the original one though there were some reports of problems. This ammunition was known popularly as " short neck ". Originally there was thought that they were cases of 7x57mm with the shortened neck, nevertheless as the diameter of the base it was of 11,95mm, today it is known that they were 7,65x54mm Mauser cases necked down to 7mm.
Provided that the majority of the cases were of Spanish origin, some suspect that this ammunition could be a remnant after Spain choose the 7x57mm.
Finally, our meritorious 7,65mm turned out to be involved in John F. Kennedy's murder. In the first hours, the CIA informed that the murder weapon was a Mauser 7,65mm confusing it with the 7,35mm Mannlicher-Carcano. Because of this confusion is unsolved, some say that it was a mistake, though this is not credible since the inscriptions in a Carcano do not leave doubts of his origin. Another version says that it was a weapon planted with dark intentions. Probably we will never know for sure.
So our 7,65x54mm it is a cartridge with great history.

The end.
