The Italian (M1906) Vickers guns were a small order from VSM Ltd., and delivered in 1906-07. Vickers also supplied the original M1906 Belts with the initial order.
Italy, however, went over to the 1914 Revelli MG (a blowback, “mousetrap” magazine fed gun, wastercooled, with a startling propensity to “cook-off” and suffer also separated cases).
In 1915, the Vickers Guns (by now in store) were ressurrected to arm the newly developed Ansaldo Armoured Patrol Cars (Ansaldo were the large Shipbuilding and Locomotove Works in Genova, which had been tasked with developing a Light armour plate for use on vehicles of their design --Ansaldo also was one of the pre-WW I Auto-makers).
The belt fed guns were more reliable than the Revelli guns and easier to feed as well.
Almost all the M1906 Vickers were assigned to the Armoured car units (used in the river plains area of the Isonzo front, as well as being sent to North Africa and Palestine).
After WWI, these cars were used during the tumults within Italy and abroad (Fiume, 1919, and possibly the Occupation of Turkey(1919-1920)). They seem to have disappeared from view in the mid to late 1920s, possibly to the African Colonies, along with their Guns.
The Vickers Guns were initially also used as Ground Guns, because the Czech Legion (expatriate Czecho-slovaks) had an “Italian” branch, which was fully armed with Italian origin equipment. Several M1906s appear in the Czech Legion display in Prague Army Museum and National Historical Museum.
The illustration of the M1906 also appears in a Colour Postcard “From the Front” of 1915, being used by Bersaglieri ( elite Light Infantry);
As to Why 200 rather than 250??? Weight considerations, as the M1906 was considered a “Light” Vickers ( well, Lighter than its Maxim predecessors).
Maybe someone searching through the recesses of Gheddaffi’s Libya, or deep in Ethiopia, will unearth some of these long Lost M1906 guns???
