The butt.
1877 if it's a Single Action Army. Nothing special about the serial number.
there are far to many #s to be a proper serial #
this question should be under Colt Firearms section
Don't know value, but made in 1926.
if double action revolver it was probably made about 1923
No serial number data published.
I found a Colt army special with that serial number being made about 1916.Don.t know the value though it would depend on it's condition.
The Ruger Old Army revolver with serial number 140-23568 was manufactured in 1980. Ruger produced this black powder revolver from 1972 until 2008, and specific serial number ranges can help identify the production year. The serial number you provided falls within the range indicating it was made in the early 1980s.
