Serial number 15541. Made circa 1918. 30 caliber with a 4.75”. This gun is in in excellent condition and a very early example as it is the 325th gun made pf approximately 17,875 guns. The Bern 1906 began production when Germany was no longer able to supply the Siss government with guns, so the Bern manufacturing started. There is a small importers mark on the underside of the frame. This is an excellent example of a 1906 Bern manufactured Luger!
