1Serial number 17. Made circa 1836-1840. 44 caliber with a 32” barrel. Very nice example! This is a very scarce example with the square back cylinder profile. This gun is pictured in The Paterson Colt Book by R. L. Wilson. Metal has nice sharp edges and clear markings with a light brown and gray patina. Stock is very good as lightly refinished. Action works well. Very Scarce early Colt long Gun! (DALLAS LOCATION)
