BROCKNOHF Solingen German Lobster 2 blade vintage automatic knife

BROCKNOHF Solingen German Lobster 2 blade vintage automatic knife made in Germany between 1945 and 1960 most likely. The knife measures just under 10cm (3 7/8 inches) open with brass liners, shackle and release tabs. One pen blade and one file blade (for fingernails). Both blades are full and the pen blade is marked BROCHNOHF over SOLINGEN and the file blade is stamped D.R.G.M. The scales look like yellowed Ivory, but most likely Ivory celluloid. The knife works perfectly with each blade popping open fully when the corresponding tab is moved at the bottom (back) of the knife. These were often sold as souvenir knives for tourists in some countries. EX condition.
