If Colt can't tell ya, aint nobady can tell ya.
I called Colt Archive Properties requesting the paper work to fill out. I filled out the paper work along with $175.00 dollars. They sent me a fax cover letter a week later stating it,s originality, and (2) weeks later I recieved a Colt letter stating It,s a 3" barrel colt python.
...frankly, I think charging $175.00 to letter a gun is outrageous, especially in the case of more modern ones where the records are quite complete and relatively easy to research.
