Aide pour identification - magnifique maquette

Hi there

I have a model of a ww1 field piece made by Bochumer Verein its a very detailed metal model with all moving parts - I am trying to identify the type. I believe it is 1:10 scale and if accurate 76mm caliber (or close to it)

• It appears the model was made around the 1st ww
• 1:10 scale 
• it has Bochumer Verein engraved on the side of the tail
• 75/ 76mm calibre going by the barrel size
• the breach looks the same as a 10cm German one (it actually works on this model) 
• elevation and traverse works
• it has a rifled barrel
• the brakes wind in and out by the handle on the front 
• the shield mount is broken so not sitting straight 

the thing I cannot seem to match to any model is the recoil system sticking out the back under the breach

The cylinders sticking out behind the breech are equilibrator cylinders. These help balance the barrel and reduce loads on the elevation mechanism. I can't give you an exact identification but it looks like a model of model of a modified 75mm Krupp export gun. Many countries bought the Krupp gun but by the 1920s the limited barrel elevation was a major issue. One of the ways to increase elevation was to move the trunnions rearwards so the breech stayed in more of less the same position regardless of elevation. However, the barrel had to be rebalanced, hence the equilibrator cylinders. The Japanese used exactly the same arrangement as this model in their 1920s modification of the Type 38 field gun (Krupp 75mm M05).

The Turks got HiH to modify their 75mm Krupp guns in the 1930s, these had the same equilibrator arrangement but newer, longer barrels. I think one of the 1920s Bofors modifications to the 75mm Krupp had this equilibrator arrangement but I can't find an image of it.
