Sterile 20cm German Secret Police Green Automatic or MCM Italian Grenade knife ERFURT

German Secret Police Green Automatic or MCM Italian Grenade knife ERFURT lockback made in Italy 1980s or 90s. I've heard them referred to both ways and have seen similar knives marked ERFURT and the blade is fired by a spring loaded bar in the blade well. These are SOLID knives and measure 19.9cm (7.75 inches) open and 4.5 inches closed with part steel, part brass backspring and heavy aluminum scales coated green with dot pattern. The drop point saber grind blade is 100% full with original finish and no markings. The green scales are in excellent condition. Knife works great with blade tip deep and centered, opens strong and tight lockup. New condition.
