yes and no on commercial guns
The police bought many commercial guns, some in 7.65mm and then rebarreled them later.
DWM made guns until the early 1930's when their inventory went to Mauser, so we would need to see pictures of the right, left, serial and unit marking (nice clear ones) to tell you absolutely what you have.
