INOX 18cm Italian Fishtail ODD Vintage automatic knife Press Button design

Vintage INOX 18cm Italian Fishtail ODD automatic knife Press Button Knife Co design with locking holes on the backside of the tang. I've had this style of knife before, but not with the locking holes on the BACK of the tang, similar to George Schrade's 1892 patent. Normally the locking holes are on the front of the blade. Not a common pattern with button near the top (front) of the knife. The knife measures 17.9cm (7 inches) open and 4 inches closed with brass liners and nickel silver button & safety cap. The spear point swedge blade is 97% full, or better with much of the original finish intact and some light scratches and sharpening marks and ricasso is stamped INOX. The genuine horn scales are in excellent condition with 3 tiny bug bites on the back scale and colors range from front scale being mostly black with white & cream streaking and the back scale mostly translucent green with black edges. The knife works well with blade tip deep in the well (channel) closed, good snap and Tight lockup open. EX condition.
