M 53
I have always liked S&W. Have 2 Model 53's, and do not know about the 22 L.R. cylinder being numbered to the revolver. Perhaps if the cylinder was shipped from the factory with the gun it may be so. Mine both have the 22 cylinder from S&W, and fitted at the factory, but they are not numbered. One is a 4 screw, the other is 3 screw. Both are full Target except 3 screw does not have RR front, 8 3/8" barrels. It would be nice to know if S&W did this. Have all inserts, bore mops not original, and do not have Red Tags.
