Developed in the 1940s the M19 was intended as the replacement with the M2 mortar. The primary change from the M2 was the introduction of a lightweight, free-aiming "spade" baseplate (later replaced with a more conventional bipod mount arrangement) and a dual function firing mechanism that could operate in both the traditional "drop fire" mode as well as a mode where the tube could be kept loaded until a spring loaded lever fired the weapon. Green paint finish overall, with a "LUBRICATION ORDER" decal applied to the tube, Bell markings on the endcap, and the aforementioned firing mechanism. Included with the lot are a green painted baseplate, M5 bipod, and an M4 sight.

Fine, with scuffs overall, along with some mild spotting. The sight is very good. The mainspring is absent from the firing mechanism, which is otherwise in good order.
