Sterile 20cm Vintage Italian Stag Fishtail Picklock switchblade knife

Vintage 1940s or 50s Italian Stag Fishtail Picklock switchblade knife. Very unique old Italian fishtail with only top bolsters. Measures 20cm (just under 8 inches) open with brass liners and nickel silver bolsters, button and safety cap. The blade appears to be about 98% full with nice dark patina. Nice thick aged Stag scales are in perfect condition and very aged. The knife works great with the blade tip seated deep and centered closed, good snap and good lockup open. Safety works. I suspect this was originally a shell puller knife with bottom/back pullers that were ground off at some point, but not positive. Beautiful old Stag Italian fishtail in EX condition.
