I am a history teacher, and a new gun owner. I started with a Taurus 856 Ultralite (Yes, I know it was a mistake, I traded that snappy thing in a hurry). Since then I got a S&W 686-1 that I absolutely adore, and quickly became a huge fan of the .357 magnum round it shoots. Well doing a little bit of digging, I found out Smith and Wesson also happened to make the first .357 magnum revolver and called it the "Registered Magnum" before renaming it the Model 27 later. I also found the first one was given to FBI director J Edgar Hoover.

My question is this, where could one find a Registered Magnum from the original 1930's run, particularly 1935 if possible? As such a huge fan of the .357 magnum and Smith & Wesson from my admiration of my 686, this would be the only other gun I would want, and purely for my personal history museum.

Thanks in advance!
