8 cm FK M 18

The 8 cm Feldkanone M 18 designed and built by Böhler was a field gun similar in size, weight and caliber to Škoda's M. 17 − Austria-Hungary used both during World War I. The majority of the M. 18 guns used the standard Austro-Hungarian 76.5 mm caliber, but testing was underway for the heavier 83.5 mm version when the war ended. However, only six guns chambered for the larger caliber had been delivered by the end of World War I.[1]

Its post-war service is unclear, but it seems that it served in small numbers with the Austrian Army, although it doesn't appear that the Germans placed it into service following the Anschluss, possibly because it used non-standard ammunition. Gander and Chamberlain don't list it in their book, but the older work by Chamberlain and Gander claims it saw service with the German Army as the 8 cm leichte Feldkanone 18(ö). A copy was also manufactured in China by Liao as "Type 14 77mm" since 1925. There seems to have been some available to the Hungarian army during world war 2. Between one and two hundred were modified by the Hungarians for installation as the main armament 75 mm 41M L/31 tank gun in their indigenous 41M Turán tank.

It was a far more innovative design than Skoda's 8 cm FK M. 17. The carriage of the M 18 had a bent axle which allowed the whole carriage to traverse since the spade pivoted around a vertical pin, so that neither the spade nor the wheels had to be moved to traverse. For use in mountains it could be fitted with a special narrow set of wheels. For transport it broke down into three animal carts.
