I inherited what appears to be a Colt, Series One, Pre-Woodsman 22 cal LR semi automatic pistol. I am a novice at firearms but have done some research which leads me to believe that this gun is from the first year of manufacture (1915) as the serial number is 641...(1 - 849 being from year 1915). Nowhere on the gun do the words "The Woodsman" appear. On the LH side of slide is "Colt Automatic Cal 22 Long Rifle". It has adjustable front and rear sights. The Colt logo appears at the rear of the slide (LH side). This gun has been in my family since the 1930's so I am aware of its history. I am not experienced enough to give a good description of its condition, although it has obviously been well used. I believe the grips to be original. Some writing on the slide is worn but writing on the barrel is very clear. OK, here's my problem. I don't want to do anything with it until I know if it is safe to use and also if it is rare enough to treat as a valuable/collectible firearm. If so, do I just take it to a local gunsmith for inspection and repairs (if needed)? I don't want to "go off the deep end" thinking that it is an extraordinary find, but I am not finding any info on specimens with such a low serial number. Do I have something here to be excited about ? Thanks.
