Tag: 7.62cm

The original 7.62 cm Pak 36, a Russian weapon, was captured by the Nazis and modified to increase the velocity. The built-up tube was rebored to seat a longer cartrige case, and a two-baffled muzzle brake added to cut down recoil energy. The breech mechanism is of the vertical sliding type, and the firing mechanism of the continuous pull type. The breech ring has been bored to seat a safety lock which holds the firing mechanism in a safe or firing position. A firing lever attached to the left side of the cradle enables the gunner to traverse as well as fire the piece. The elevating handwheel is generally situated on the right side of the cradle. Two puller type equilibrators located under the front of the cradle and attached to the rear by chains compensate for muzzle preponderance.

The carriage is of welded steel construction with synthetic filled pneumatic tires and split trails, which can be spread to an angle of 60 ° for firing. The hydropneumatic recoil system consists of two cylinders, one for recoil and the other for counterrecoil. This model is semi-automatic in operation.

The weapon is reported to use the following types of ammunition: A.P.C.; H.E. A sight bracket is attached to the left of the trunnion, and the German range indicator is graduated for the types of ammunition mentioned above.

This gun, recently captured in Sicily, has the general simplicity of design characteristic of most Russian weapons. This was formerly a Russian piece, modified by the Germans to use Pak 36 (r) ammunition. The tube which is provided with a jacket is shorter than the Russian 7.62 cm F.K. 36, and is fitted with a double baffled muzzle brake, similar to that used on the 7.5 cm Pak 40. The breechblock is of the vertical falling block type, and appears to be wholly hand operated.

The buffer is located inside the cradle, whereas the recuperator is mounted above the piece. On recoil, the recuperator cylinder moves with the barrel, the piston rod being attached to the upper end of the bracket which is secured to the forward end of the cradle.

Sighting gear consists of a range drum (calibrated for use with Pz. Gr. 40 and Pz. Gr. 39 ammunition) and dial sight carrier mounted on the left trunnion. There appears to be no provision for a telescopic antitank sight.

Traversing and elevating mechanisms are operated by handwheels on the left and right hand sides of the gun.

The weapon is mounted on a crosshead consisting of a short hollow rectangular shaft provided with bearings at either end for the trail heads. The split trails, constructed from rectangular girders, are operated by traversing handles secured to each trail end. Wheels are disk type with pneumatic type tires filled with synthetic.

The shield is a single flat sheet of metal cut away at the lower corners for the wheels. The top is curved upward to the center where there is a sliding center piece over the barrel. A rectangular sighting aperture with sliding cover is cut out on the left hand side in front of the dial sight carrier.
