Jim, do you have any thoughts?

I'm pretty sure the 3D----31651 are assembly and inspection numbers.
The number on the underside of the grip butt is the standard serial number location. During the 80's/90's S&W sometimes also stamped the SN in the yoke cutout location but it would have been a single line. That, and having two completely different SN's is very unlikely.
