Do you know if S&W did any short action conversions like this Ralph?

I can't imagine the hammer modification didn't happen in conjunction with the short action job.

Looking at this gun one of the things with the S/N on the rear sight that I think is worth pondering is that this is a 2 screw sight, which I think was mid 1930s? I forget exactly when those came in, I am sure someone can remind me what year that was.

That should date when the conversion to a "Virtual Outdoorsman" was done. I'm excited to see if the Historical Foundation has some records on this.
