This color educational/promotional film is about the Bofors 10.5 cm Field Howitzer L/28. The Internet has scant information on the L/28, but it was apparently designed for rapid movement and positioning, and the narrator notes that it was intended to be positioned quickly so as to hold off a paratroop or partisan type attack. Whereas prior to WWII Bofors had developed a 10.5 cm howitzer (also known as the Model 1924), this model appears to be different and may have never gone into volume production. Like the M1924, this howitzer was designed for motor traction with rubber-rimmed steel wheels. It had a firing platform that gave it 360° traverse. This gun appears to be a light version of the 10.5 cm kanon m/34, a heavy field gun produced in Sweden and also designed for motor towing. The m/34 was a development of the earlier 10.5 cm Cannon Model 1927, with the carriage being used by various Bofors 15 cm howitzers of the 1930s. No copyright but this is circa the 1950s/1960s.
