Does anyone have information on the 37 mm HanL/28 infantry gun produced in the early 1930's. it was a varient of the Mukden 37mm type 14 with a strange carriage(the front legs formed a sawhorse type stand when the wheels were removed.) and had an interrupted screw block breech. The Mukden gun was apparently a copy of the Japanese 37mm Sogekiho inf. gun and was written up in a Japanese intelligence report.
