Here is part of one paragraph from a brief history of the Victory Model I wrote on December 7, 2016, to commemorate the 75th Anniversary of the Pearl Harbor attack. This information was largely drawn from Pate's book.
Through the first eleven months of 1941, the U.S. military establishment was acquiring the commercial version of the .38 M&P revolver (.38 Special chamber), mostly for stateside security services, especially at ordnance depots and ports. Most of these guns were acquired through various purchase orders. The largest known example is a U.S. Navy request for 3,000 revolvers that were to be issued to the U.S. Naval Civilian Police Corps. The formal request for this purchase is dated January 4, 1941, and specifies that the backstrap of the gun is to be marked U.S.N.C.P.C. Company records reveal that all of the requested guns were delivered in ten shipments beginning on March 14 and ending on May 10, 1941.
