This is a very nice Case XX 1940-64 serpentine 2 blade jack knife. Number 62087. Handles seem to be greenbone. The 6 in the number is worn away. There seems to be an age crack at the front side top pin. Doesn’t look to be all the way through. Handles very nice and tight. This is a very nice old knife. Please check pictures carefully and you can be the judge. Ship by ground advantage. No international sales.
