What is the history of the little three point, coin size screw driver with the Colt logo on it. I was looking through a nice Colt collecton a few days back and noticed on of these items as part of a "New In The Box" Pocket Positive. I asked the collector if that screw driver came in that box? and he related that it was in there when he traded for it back in the late thirties.. Did these screw drivers come in all new Colt purchases, if so when did they start and when did they stop??????? Thanks..
