My EDC looks like a 649, but is a 60's 49 no dash that was "Metal Life" refinished before I got it. Mine had worn smooth Pac on it when I bought it and put "Bananas" on within two hours! Metal Life is a type of Teflon finish that came in many colors. My gun has some of the interior refinished also. With a full power main spring it is so smooth, you think the spring is cut!
Back in the ancient times of the 50's & 60's criminals weren't as tuff, as the J-frames of that era were only 38 Special. And from post WWI to the 50's you only needed a I-Frame in 32 S&W Long or 38 S&W (Regulation Police/Model 35) to ward off the evil minions! The 357's of that earlier era were for bear hunting! My how thugs have changed!
