The FK 18 was significantly lighter than the older gun, but was otherwise an unimpressive weapon. It used a modern split trail carriage, with the rear section and spades folding upwards for travel. It used the typical German recoil system, where the hydraulic buffer was housed in the cradle underneath the barrel and the hydro-pneumatic recuperator in a cylinder above the barrel. For some reason, the FK 18 was unusually prone to bore damage from cartridge debris, and the barrel had to be inspected after every shot to ensure it was clear. • Illustration — A Brazilian gun on wooden wheels with a limber draught by horses • Illustration — A modernized version of the gun on pneumatic tires in a Brazilian museum • Illustration — Bolivian FK 18 under tow in Cochabamba
