The main difference between the 82-PM-37 and the earlier 82-PM-36 was the adoption of a round base plate, revised traverse/elevation controls, simplified sights and spring-loaded shock absorbers on the bi-pod to reduce the amount of relaying needed between shots. It was designed to be able to fire western 81 mm captured ammunition whilst not permitting the enemy the same advantage The German designation for captured M-37 mortars was 8.2 cm GrW 274/2(r) .^[source]82-BM-37 · Lead; only the objects and conditions stated in this passage The M-37M is an improved version with a lighter base plate and a device to prevent double loading.^[source]82-BM-37 · Lead; only the objects and conditions stated in this passage
