Mine are all handmade from 1951-1963 except the 1973 Texas Rangers and the Model 10-5 that I bought 40+ years ago. All are .357 except the .38 Special.
I had a post-war K-22 Masterpiece (~1946) that I bought years ago. It was a LERK (large ejector rod knob). S&W never liked to throw away parts so the rods were carry over from the pre-war revolvers. It didn't change the gun just made it rare. I sold it later to fund another purchase. Great guns and fun to shoot....All passed down to me from my Dad. Love nor money can get this one. I was with Dad the day he got this one. Many, many rounds shot thru this gem. Still the most accurate gun that I own.
