G SCHRADE arched Pullball Cream scales Green ball vintage automatic knife

Geo Schrade Knife Co pullball switchblade with cream handles made in Bridgeport, CT. This is an earlier knife with the arched G SCHRADE B'PORT, CT stamp and the back of the tang PATS 11-9-27 10-19-44 which are both wrong dates. Not sure why, but most of these seem to have the wrong patent dates. The knife measures 2 7/8 inches closed and 5 inches open with brass liners. The blade is full with original finish and light scratches and stamped as stated above. The Cream synthetic handles are in nice condition with slight shrinkage and green pullball. The knife works fine and is in EX+ condition.
