Military and LEO guns are notorious for having the wrong numbered stocks installed. Armorers who were taking apart "tools" cleaning and lubricating or making minor repairs or adjustments did not care if the stocks went back on the same numbered gun as long as the "tool" functioned for its intended purpose.
I have long suggested the establishment of the "S&W Stock Exchange" because there seem to be so many S&W's that are not wearing their original slippers out there. As the OP suggested this would merely be a swap between owners in an attempt to reunite wood and metal without focusing on profit. Not sure how one would deal with poor condition stocks being traded for excellent condition ones but perhaps some monetary adjustment could be made.
Not sure how much bandwidth this would require as that is above my pay grade but it sure seems like a neat idea. How many times do you read about a S&W for sale and the seller states that the stocks do not match the gun??????
Great idea IMHO, just needs someone smarter than me to set it up.
