Historic and technical information
Denomination :     10cm M 99 GebH Origin :       ( Arsenaux d'état)          

Historic context :

As an essentially mountainous country, Austria was wanting to be equipped with a powerful mountain artillery. The usual calibre of the 7 cm mountain light field guns was found to be insufficient in some circumstances, so that a higher caliber 10 cm mountain howitzer study was started. Doing so, Austro-Hungaria was the very first country to introduce such a weapon.

This is how the '10 cm Geb.H M99' mountain howitzer was born, with a rigid carriage with a low and narrow profile (wheels diameter and distance 90 cm), on which the bronze barrel of the '10 cm FH M99' field howitzer was adapted with its 'Nemetz' eccentric screw type breech. The gun could be dismounted into 2 separate loads for transportation. Just as the field howitzer, it lacked any kind of modern recoil recuperation system and only had a not so efficient spade spring instead.

Austria had to wait for the design of the '10 cm Geb.Haubitze M08' to solve this issue and finally have a modern mountain howitzer.
