PATENT ROSTFREI Vintage 21cm Italian OTF DA automatic knife New Old Stock

Vintage PATENT ROSTFREI Italian OTF DA NOS automatic knife direct from Italy last year along with several other New Old Stock knives from the 1970s that were found in a box in Italy. I believe these were made in Maniago by Rosa Uliana Primo. The knife measures 21cm (8 5/16 inches) open and 5 inches closed. The flat spear point blade is 100% full with all of the factory finish intact and is stamped PATENT ROSTFREI on the ricasso. The frame appears to be non-magnetic cast, but more likely chrome plated brass and the button is also metal and pinned. The black synthetic scales are in excellent condition with some light handling marks on the scales. The DA (double action) knife functions great with blade shooting out when you push forward on the knob and closing when you pull back on the knob. NOS condition with minor imperfections.
