I know this is little information for the question, But, what is the value of a 1959 357 Flat Top Blackhawk with a 10" barrel. I don't have a picture to show but I believe it to be a 88-90% gun. Blueing is good, grips are good, lock up and end shake is good. Very light, hardly noticeable, turn ring. Has a very good trigger and not converted. The only down side I saw on the gun was the previous owners initials and a date on the frame in front of the trigger guard on the bottom. Very small letters. I have heard mention of a OM Flat Top with a 10" pipe but this is the first I've seen.
