60mm M57 Yugoslavian Mortar      

60mm M57 Mortar

The Yugoslavian 60mm M57 Mortar was generally based on the design of the US 60mm M3 Mortar.  The breech piece, which is threaded into the barrel, has a ball fitting to mate into a rectangular base plate.  The mortar is a conventional drop-fired mortar with a fixed firing pin. The bipod has a cross-leveling gear operated by a threaded sleeve between one leg and the elevating gear. This is attached to the yoke, which carries the traversing screw and the shock-absorbing spring cylinders. The 60mmM57 is fitted with the NSB-3 sight.
