25cm Spanish Pig Sticker Vintage 1960s Automatic sheath knife w guards

Vintage Spanish Pig Sticker Automatic BoBc sheath knife with folding guards made in Spain most likely in the 1960s or 70s. It measures 25.3cm (10 inches) open and 6.5 inches closed with steel liners and nickel silver plated bolsters, guards & button. The bayonet style spear point blade is nearly full with much of the original finish and lots of light scratches from sharpening/use with no maker's mark that I can see. Might have originally been lightly etched Toledo. The scales are Brazilian horn and in very good condition except for one missing chunk on the back scale near bottom. Scales range in color including Black, green, tan, honey & cream. The knife does open automatically thought it's a little slow opening and opens fully and locks open with about 1/4 inch up and down at the tip. The matching leather sheath is in fair condition and missing the strap with snap, but does have the belt loop. VG- condition.
