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 cheekpiece, and an adjustable rubber recoil pad. The left side of the receiver bears the military nomenclature and "VKT" logo. The barrel is mixed numbered ("691"), with other visible external numbers matching the receiver. Included with the lot are two extra magazines.

Fine, with 80% of the original blue finish, showing areas of brown patina, flecking of what appears to be white paint, and mild handing marks. The barrel shroud shows splits and cracks, and a screw is absent from the cheekpiece, otherwise the furniture is in good order. Mechanically excellent.
