Can't tell from the information you gave- which is that you have a .32 ACP caliber pistol made in Erfurt Germany. But if you have a DWM (Deutsche Werk und Munitionsfabriken) Pocket Automatic (similar to the FN Browning Model 1910) they were made from ABOUT 1921-1931. In good condition, about a $450-$500 pistol.
