A freind of mine called and told me ha found a old colt in a desk inherited in a old desk from his grandfather. Here are the markings on the gun, hope you can help! On the top of the barrell it shows,(or the best we ecan tell) ANRESS SAMl COLT, on the bottom, NEW YORK CITY.It's a very unique gun. It obviously uses a cap , and is a 6 shooter. Any help would be greatly appriiciative.
