Just got back from the gun show with my latest find and had a question.The dealer said that this is a Lew Horton revolver.The serial number checks out,but the sights are wrong.According to the Supica book,it should have red ramp and white outline sights,but this has a pinned plain front and plain rear.Also,it lists the Horton guns as 624-2,but this one is a 624 with no dash.Any ideas?
