There are so many things unusual about this gun that we will never come close to identifying it without some photos. A gun dated 1913 and with a serial number of 356a would not have a grip safety unless it was converted, and that would require a different sear bar plus the safety marking (GESICHERT) would be in the wrong position. A 30 Luger barrel with a small cross is almost certainly a Swiss, but it would be threaded for a long frame/receiver and wouldn't work with a 1913 military short receiver without shortening the threads and rechambering. What is the length of the barrel? Just poke something thin enough to go down the barrel and measure the distance front of the breech block to the front of the barrel. Please provide some photos or just shoot me and put me out of my misery.
