..thanks so much....
However...
"In May of 1960, the .22/32 Model 51 Rim-fire Magnum Kit Gun was introduced, chambered for the .22 Winchester Rimfire Magnum. The 51 was S&W’s initial entry into .22 magnum Kit Gun production and began with serial number 52,637. These were made only on the J-frame and 4” barrels, produced until 1974."
51s had a 3.5" barrel like the 43....
I've owned most of the models mentioned... The only ones I have left are a 63 with an extra .22 Magnum cylinder and a Model 35 also with an extra Magnum cylinder...unless you also want to count the 317....the UltraLite Kit Gun...
