Dutch Schwarzlose MG M. 08/13 - 6.5×53mmR

The Schwarzlose machine gun is a water-cooled, belt-fed machine gun designed by Andreas Wilhelm Schwarzlose for the Austro-Hungarian Army in 1907. Following the release of the Maxim design, many states of the world placed orders with the large manufacturers Vickers and DWM or applied for their own production. The K.u.K. monarchy of Austria-Hungary took another path. Around 1902, the Berlin engineer Andreas Schwarzlose had applied for a patent for his own machine gun design. Steyr-Werke acquired the license in 1905 and in 1907 it was introduced in the Austrian armed forces as the M.07 in the caliber 8x50R. The model of 1907 has a gap between the top cover and the water jacket. This was changed with the MG M. 7/12. Some improvements after 1912 led to the version M.07 / 12.

Schwarzlose, who had previously attracted attention through technically highly interesting constructions in the field of weapons technology, took a completely new approach. His MG had a fixed barrel and is based essentially on the functioning of a delayed spring-mass closure. During the shooting process, the spent cartridge blows back the bolt rearward, but without locking it, thus giving a momentary delay. During this delay, chamber pressure drops enough to be safe. The use of a strong recoil spring along with a heavy bolt and series of levers led to retarding of the rearward motion from recoil, ensuring in conjunction with its relatively short barrel that the bullet exits the weapon before recoil forces move the bolt back and dissipate the high pressure left behind. A small blemish on this ingenious design is the need for an oil pump, which was considered necessary to prevent problems with extracting cartridges. An oil filling of five liters was enough for about 4,500 cartridges. The Austro-Hungarian Aviation Troops were equipped with the M.07/12/R16, which was an air-cooled version of the M. 7/12. During World War I, Austria-Hungary exported the MG M. 7/12 to Bulgaria and the Ottoman Empire.

The nature of the construction initially suggests that the Schwarzlose MG relies too heavily on given functional parameters such as caliber, laboratory and, in particular, run length, to be easily adapted to other versions of the same caliber or other calibers. Interestingly enough, however, the MG was successfully designed to use such different calibers as the improved cartridge M.31 (Austria, Hungary after 1931), 6.5mm Mannlicher-Schönauer, 6.5mm Swedish or even 8mm Mauser.

It was used in the two world wars and then on many fronts, from Scandinavia to North Africa.

Manufacturers were from 1905 to 1918 Österreichische Waffenfabriks-Gesellschaft (OeWG), Steyr and from 1914 to 1918 FGGY in Budapest. Another manufacturer (Artillery Inrichtingen, M08, about 2000 pieces) was in Holland based on the M.07 under the names M.07, M08/13, M08/15 and chambered in 6.5×53mmR. In Sweden, it was manufactured by Carl Gustav as the Kulspruta M/1914 (which looks exactly the same as the M. 7/12, but has the Swedish national coat of arms on the water cooling jacket) and was used for decades in the Swedish army. It adorns to this day the medal of the Swedish MG gunners.
