ARE YOU SURE IT'S A 24-3? The -3 series was the 1983 reissue of the Model of 1950 44 Spl. and the revolvers were offered only in blue. If it is a 24-3 in nickel, check the extractor star, which should be blue; otherwise, it's a change of finish job and not original. The current series of Model 1950 re-issues are stamped 24-6 and are offered in blue and nickel. I suspect your friend is offering the -6 change model.
Cheers,
