Changing of vehicle designs and establishing of systems for supplying previous model parts for repairs

As improvements and reforms had not been carried out during the war, immediately after the war, in November 1945, work began on designing a new model truck. Prototype production started in April 1946 and production of the Model BM truck commenced in March 1947. Although there were changes to the design and some fine-tuning of the Model KB 4-ton truck that had been developed in March 1942, major alterations could not be made. The specifications of the BM 4-ton truck are shown in Table 1-20. By July 1951, there had been 26,347 Model BM trucks produced.
