Introduced in 1939 and rushed into service for the Winter War, the Lahti L-39 fires a 20mm anti-tank round from a top-loaded magazine and was capable of successfully engaging the Soviet armor of the era. It was fielded under the nomenclature "20 pst kiv/39" (as seen on this example). Measuring taller than a man and weighing in at close to 110 pounds, the L-39 is fitted with a ported muzzle brake, a long vented hardwood barrel shroud, left-offset blade and tangent sights, a dual-mode bipod with brass covered wood skids and swing-out spiked legs, crank-action cocking handle, smooth hardwood grips with an oversized steel handguard, wooden cheek piece, and an adjustable rubber recoil pad. The left side of the receiver bears the military nomenclature, "VKT" logo, and "SA" Finnish Army acceptance mark. Included with the lot is a transport case, five metal magazine cases and ten extra magazines.

Very fine, with 80% of the original blue finish, showing areas of brown patina, a plum tone to the barrel, and mild handling marks overall. The cheek piece and barrel shroud show a number of scuffs and dents, and the bipod assembly shows a strong green paint finish on the upper surfaces and exposed aged brass on the bottom and edges of the skids. The recoil pad is scuffed and torn. The case is rough, with the magazine cases showing wear appropriate to age. Mechanism is stiff, but appears to be in good order.
