Spanish 23cm INOX Bolster Button automatic knife with finger guards

Vintage French bolster button automatic knife with black checkered scales. The knife measures 23cm (9 inches) open with brass liners and steel bolsters and button. The flat grind blade is nearly full and retains most of the factory finish with some scratches and is stamped 290960 INOX (not sure on the 4th number?). Looks like someone tried to add a small swedge grind near the tip. Doesn't take much away from this nice Spanish switchblade. The scales are checkered black plastic and in very nice condition. The knife works well with the blade tip seating deep when closed, good snap from coil spring and good lockup. Safety works, but it's a little hard to get into the safe position. VG+ condition.
