8 cm FK M 18

The 8 cm Feldkanone M 18 was a field gun used by Austria-Hungary during World War I. The initial 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 had been delivered by the end of World War I. 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).

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.
