Once upon a long ago...
I had such a revolver. A four screw S&W Combat Magnum, possibly an early Model 19. I sold it as consequence of an attack of poverty occasioned by the onset of marriage.
Sigh...
Enjoy that revolver. It wants, deserves and needs to be loaded with 158 grain SWC bullets over a stiff charge of 2400 - or something much like it; carried and shot from time to time, as needed.
Just for comparison. I just saw one last weekend at a gun show in Grand Island, Nebraska. It was a four screw, marked 'model 19' without dash and had the proper diamond grips. Asking price was $1200, U. S. Yankee money. I shed an internal tear if not external.
Sigh...
