Wow, PhilOhio!! I thought I had an early one; mine is Sn 9981. Couldn't have been too far behind yours, particularly since Model 39 serial numbers were also in this series. It still has the orignal box and papers. I got the aftermarket weights for it, but found even at the age of 22, after a season of competitive shooting, they were still too heavy for my hand. It hasn't been around the world but did spend a year in an arms room pistol rack in Thule, Greenland.
