A CENTAZZO MANIAGO 20cm Italian Shell puller Imitation stag vintage automatic knife

A CENTAZZO MANIAGO 20cm Italian Shell puller Imitation stag vintage automatic knife made in Italy 1960s or 70s most likely. The knife measures 20cm (7 7/8 inches) open and 4 3/8 inches closed with steel liners & bolsters and nickel silver lever. The spear point blade is 99% full, or better with patina, scratches and some scattered pitting and the ricasso is stamped A CENTAZZO MANIAGO. The handles (scales) are synthetic fake stag and in excellent condition, but unfortunately someone ground off the shell pullers. The knife works well with blade tip just above the liners closed, strong snap and very good lockup with about 1/16" down at the tip that springs back when you let go. No rattle if shaken with blade open. G+ condition.
