It consisted of a barrel of the 10 cm Feldhaubitze M 99 made from the so-called steel bronze (92% copper bronze strengthened by autofrettage which was used due to the lack of steel industry in Austria, see Franz von Uchatius) on a new, narrow-gauge box trail carriage that could be broken down for transport on animal carts. Like its brother, it lacked a modern recoil system, using only an ineffective spring-mounted recoil spade, and was virtually obsolescent upon its introduction. Relatively few were made as the version of the standard 10 cm Feldhaubitze M 99 with a narrow, 1.3-metre (51 in) carriage was cheaper.
