Long before the First World War, in the middle 1909, to conduct the comparative trials the Shneider's 42-linear (1 line = 0.1 inch, so 42 lines = 4.2 inch or 106.7 mm) gun on the high gun-carriage was delivered to the tsarist Russia and then, in October 1909, the Krupp's 42-linear gun was delivered as well. By the middle 1910, both guns were tested and showed satisfactory results, but by unknown reason the Shneider's gun was chose. However, the commission of the Russian artllerists and experts made an order to pursue some (the exact number is unknown) Shneider's guns mounted on low gun-carriage (1372mm vs 1829mm). The gun on low gun-carriage was much lighter, but its recoil run was dropped from 1500 mm to 1100 mm. The Krupp's gun was sent back to the Germany as the Krupp Corporation request. The Shneider's gun was accepted for service and named "42-linear heavy field gun model 1910".

In January 1913, the France accepted for service the same gun, but re-bored on Shneider's factories to 105 mm calibre. Some re-bored (105 mm) guns were sent to the Russia where they were re-bored again to 106.7 mm calibre, then accepted for service and named "107 mm improved gun".

Curiously that two hundreds 107 mm guns model 1910 were ordered in Italy. In September 1917, these guns were accepted by Russian inspector in Monado, but they weren't delivered in Russia and their future is still unknown.

In 1914, the Putilovsky factory was ordered to manufacture the two bunches of 107 mm guns: the first bunch of 50 guns and the second of 265 guns. By 1916 the first bunch was ready, but the second was done partially. Only 174 guns and 172 gun-carriages were manufactured by November 1, 1919. In 1920-1927, additional 3040 guns were manufactured.

On July 27, 1912, the Orudijny (Artillery) factory in St.Peterburg signed the contract to manufacture 100 107-mm guns model 1910 not later October 1917. Factory had manufactured 12 guns by January 1916, and additional 15 guns by 1917. After that, the factory was relocated from St.Peterburg to Mytishi (a town near Moscow) and until 1925 it didn't produce any guns.

In June 1915, the Obukhovsky factory receive an order to manufacture 400 of 107 mm guns model 1910. The order must been accomplished by April 1919. Below you can see how the order was accomplished in fact:

In 1913, the Russian Army had 19 heavy batteries, each armed with four 107 mm guns model 1910. By the beginning of the First World War all these batteries were intact and additional two batteries were in reserve. Besides, by 1915, there were 23 of 107 mm guns distributed in 5 fortresses. By June 15, 1917, the Russian Army had 189 of 107 mm guns plus 43 of ex-Japanese 107 mm guns model 1905 being captured during Russian-Japanese War.
