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.
0-100 USD or so
when was the Deutsche werk werk erfurt 22 single made and what is the worth? I was told by a gunsmith that they were made sometime after WW1 for export to improve the trade balance for germany. They were mass produced and sold cheaply. They mostly have sentimental value. It was the first gun I ever fired when I was 6 years old. I still have it and am now aged 69.
What would you like to know about this pistol? I've done quite a bit of research on these.
Impossible to answer without a detailed description of ALL marks.
5-100 dollars
10-100 USD or so
50-1000 USD or so depending on specifics
