I have been looking at these for a while but the prices were a little more than I wanted to pay. This one popped up with a Buy it Now price that I couldn't say no to. These were built, originally by Heinrich Ortgies, and later by Deutsche Werke, from 1922 till about 1928. It's a 7.65/32auto caliber. It is a very tight solid little gun, and shoots very accurately considering the tiny little sights. I have a feeling this one might see quite a bit of use.
