English: Steel barrel, threaded, without muzzle brake. Wedge lock with horizontal movement. Hydraulic resistor and pneumatic returner located under the barrel. The gun guidance mechanisms are placed on both sides of the barrel and adapted to work with the Luftværnskorrektør M.1932 central camera or the Luftværnskorrektør M.1938 central camera. The cannon was placed on a fighting position on a four-support cross bed. During transport, the gun tails were connected together and attached to the fore-end, and a single-axle trolley equipped with shock absorption and metal wheels with a vulcanized layer of rubber (so-called hollow blocks) enabling transport by motorized traction was attached to the central part of the bed. The gun crew consisted of 1 officer and 10 non-commissioned officers and privates.
