Some references are saying the butt of the handle and some say inside the hinge.On the grip butt there is a prefix of AEJ which I find no reference. The revolver is stamped with model 36 inside the hinge which I see means after 1957.
The revolver should have an S in front of the serial number if it's an N frame from that period.
I've noticed in the past S&W revolvers have numbers stamped several places.
Until now I really had no need to know which one was the serial number. Highway Patolman which appears to be a Model 27 without being identified as so.
Further study shows the subject to be of almost unbelievable complexity." Homer Powley Thanks Nick and Marshal. All Smith and Wesson revolvers (well, at least the hand ejectors) have a serial number on the butt. It is possible the Highway Patrolman is pre model 28.
If the crane recess is stamped with a model number it is so light he can't detect it , even with a magnafier. If the gun is an N-frame and has a checkered topstrap, then its a Model 27.
