Jndiana PATENT 18cm Pattada Italian Birds head Horn brass switchblade knife

Vintage Jndiana PATENT 18cm Pattada Italian Birds head Horn brass switchblade knife most likely made in the 1970s or 80s. It measures 18cm (7 1/16 inches) open and 4 inches closed with steel liners and brass bosters, button safety cap & pins. The straight back blade is 100% full with original matte lined finish and the ricasso is stamped with the Jndiana Mountain stamp and the reverse is stamped PATENT. I'm pretty sure that the scales are ivory colored horn and in great condition. As is with most of these knives it works great with blade tip deep in the well closed, strong snap and great lockup with just a hint of movement at the tip. Does NOT rattle if shaken with blade open. Safety works. EX+ condition.
