George Schrade Knife Co pullball Cream in box

Geo Schrade Knife Co pullball switchblade in box that I believe to be original to the knife. This is an earlier knife with the arched G SCHRADE B'PORT, CT stamp and the patent dates of 11-9-27 and 10-10-44 which interestingly are the WRONG dates. They put two different sets of wrong dates on these knives as well as some with the correct dates. This seems to be the rarest stamping based on my experience. The knife is in EX+ condition with a full blade with all of the original factory finish intact. The Cream synthetic handles are in nice condition and show a little handling with the initials R. C.  on the front scale. The knife works perfectly.
