Are you sure it sez "Police Positive"? Annual production serial numbers for the Police Positive .38 model range from #1 in 1905 through 406725 in 1943; I don't have the serial numbers for 1944-47, but I don't think they made another 190,000. The series numbers were also shared with the Bankers Special and Police Positive .32 models. Your serial number possibly corresponds to an Official Police or Police Positive Special model. In any event, it most certainly was in service in another country. Hope this helps some.
