COLORADO SPRINT INOX 22cm Italian OTF DA etched automatic knife

COLORADO SPRINT INOX 22cm Italian OTF DA etched automatic knife made in Italy most likely in the 1970s. The knife measures 21.7cm (8 5/8 inches) open and 4 7/8 inches closed with polished aluminum frame. The flat spear point blade is 100% full with original finish and is etched COLORADO SPRINT INOX on the face. The smooth black synthetic inserts are in very good condition with slight shrinkage and held on by brass screws. The knife works perfectly with blade opening fully and locking when the switch (button/knob) is pushed forward and retracts fully into the frame when it's pulled backward. EX+ condition.
