I have the SW catalogue and have been to the home site.
Where is the best place to find actual production numbers or SW semi-autos. I have original boxes for most of my smiths.

I'm not aware of any production #'s available outside of S&W except on some of the PC guns. If you find that info you have done better than me!

Others who know more may chime in...

are you familiar with the gun sheets you can request (pay for) from S&W? what information do the sheets provide?
