MIKOV 20cm CZECH Republic 1960s vintage OTF Green Pearlex DA automatic knife

MIKOV 20cm CZECH Republic 1960s vintage OTF Green Pearlex DA automatic knife measures 19.5cm (7.75 inches) open and 4 5/8 inches closed with aluminum frame. The flat spear point blade is 99% full or better with original finish and no markings (sterile). I have seen these etched Mackie/Mikov anticorro (stainless steel), but I don't think this one was ever etched. The green pearl & black kirinite scales (handles) are very attractive and in great condition. It comes with a custom zippered sheath. The knife works perfectly with blade opening fully and locking when the switch (button/knob) is pushed forward and retracts fully when pulled backward. EX+ condition.
