Great article. My only comment is that I think you are a bit off with the initial serial number. I have S106374 which left the factory in May 1954. I always thought the first Highway Patrolman was S103500.
Here is the thread for my gun.

Once again, I need to point out that guns were not usually completed or shipped in serial number order. Serialed frames went into bins, and were pulled out for completion and then shipment quite randomly. Also, all N-frame serial numbers were intermixed. Production batches commonly ran from 50 to 300; quite possibly more. It's not unusual to find an earlier serialed gun shipped later than one numbered higher. Never confuse serial numbers with shipping order at S&W. I made an earlier post in this thread about that, and cited a couple of examples of this that I personally own. You have a nice early Highway Patrolman, but the serial number is largely immaterial to when it was shipped. See posts 30 and 40 in this thread.
The serial number S107,500 comes from Roy Jinks in his book The History of Smith & Wesson as being the first production gun. Roy has to be the final authority on that, citing April 15, 1954 as the completion of the first run of production guns.
