Argentina 25cm Vintage Flat guard Ringpull picklock made in Argentina

This is one you don't see very often. It's an old flat guard picklock with rectangular button and safety! The knife measures 25cm (10 inches) open with steel bolsters and plated metal bolsters, button and safety. I suspect that this knife was made in the 1950s, or before. The blade appears to be mostly full and is marked INDUSTRIA ARGENTINA with heavy patina, scratches and spotting. The horn scales are translucent yellow/green and in good shape with one hairline crack through the top pins in the front scale. The knife works well with the blade tip even with the liners when closed, nice snap and very good lockup open. Very cool old 10 inch flatguard switchblade!
