 At least 16 were modified for motorized traction, presumably with steel wheels and pneumatic tires, for service with the Light Division.Gander and Chamberlain claim there were three almost identical versions, the M 02/04, OM 04 and NM 10, but this has not been confirmed.The Germans designated these guns as the 7.5 cm Feldkanone 243(h) after the Battle of the Netherlands.
