GEORGE SCHRADE Pullball Black switchblade General Electric knife

Geo Schrade Knife Co pullball switchblade with black scales and green translucent ball. This is an earlier knife with the arched G SCHRADE B'PORT, CT stamp and the patent dates of 11-9-27 and 10-19-44 which interestingly are the WRONG dates. Should be 11-9-37 and 10-10-44. They put two different sets of wrong dates on these knives as well as some with the correct dates over the years. This seems to be a less common stamping based on my experience. The knife measures 2 7/8" closed including the ball and 5 inches open with brass liners. The blade is mostly full at about 95% and shiny with some light scratches. The Black synthetic handles are in good condition and show a little handling and pocket wear with advertising: GENERAL ELECTRIC CO CONDUIT PRODUCTS DIV and a nickel silver shackle. The knife works well and is in VG condition.
