RARE Brevete SGDG 21cm French OTF REVERSE lever vintage automatic knife

Very RARE Brevete SGDG 21cm French OTF REVERSE lever vintage automatic knife made in France in the 1960s or 70s. Most OTF automatic knives open buy "pushing" the knob forward, but this one opens by "pulling" the knob backwards!

It measures 21.1cm (8 3/8 inches) open and 4.5 inches closed with brass liners and steel bolsters with aluminum knob (button/switch). The flat spear blade is 100% full with original finish and no markings on the blade. The black synthetic checkered handles (frame) are in excellent condition with minimal shrinkage. Both scales have raised letter stamp at the bottom (back) that reads "BREVETE SGDG MADE IN FRANCE". The knife works Great, backwards, but Great with blade opening fully and locking when you "PULL" the button back and closes completely when you "PUSH" it forward. Other than some tiny scuffs on the blade it would be near mint condition.
