Rare German bayonet, so called “Haenel 1907”. It was a modification on Mauser 88 produced for China. At the begining of WWI many of those were still in Germany and were used by Landsturm (National Guard) together with bayonets like this. It closely resembles Portugal 1904, but there are different markings and muzzle ring diameter. Also the finish of the blade is slightly different.
