The first WWII civilian MS truck was produced on January 3, 1944 as serial number 9MS25-2127 not 1001. The last tag I have is 9MS42 29235 (June 45). On September 1, 1945 the interim trucks came out they were a continuation of the regular 1942 lines but the model prefix change and their production numbers started at 1001 (9OS09 1001 1 1/2 ton). So, I would say a rough guess is 31000 MS trucks were built during WWII
