S.M. CO 33cm Italian Picklock 1950s vintage automatic knife

Vintage SM CO 33cm (13 inch) Italian picklock bayonet horn automatic knife made in Italy in the 1950s. The knife measures 32.7cm (12 13/16 inches) open and 7 1/8 inches closed  with D stamped brass liners and nickel silver bolsters, button and safety cap. The bayonet style blade is about 1/4 inch short and about 95% full with heavy patina and scratches and is stamped S.M.CO ITALY. The horn scales are in good condition and mostly Honey, Cream & brown in color with one small damaged area on the back scale. The knife works GREAT with the blade tip even with the liners closed and centered, good snap and excellent lockup with just a hint of movement each way at the tip. Short throw safety works great. VG condition.
