As FYI, the quality of the first SAC gun I saw, an early AE grade, was the reason I got "hooked" and have since devoted so much time to research. In my opinion, the early SAC guns were the best fitted and finished; but as a collector, all examples seem to catch my interest. In comparison to the higher grade SAC guns, the low grades are indeed very plain; but your Grade O gun represented a lot of quality at a $30 list price. I hope this is the first example of many you will acquire.
