I'm sorry, yes the safety. Did this at work and got distracted. The three variants were: safety inside trigger guard, safety behind trigger guard, and then safety mounted on upper tang behind action. From my reading, I'm seeing production beginning in 1904 and ending (for the 520A) in 1932. WWII briefly restarted production of the 520A as a trench broom. I'm seeing claims of the first model changing about 1920, with next change around 1928 (when they went to the one-hump receiver). I am told by one of the venerable members here that the Stevens production records were lost in a rather suspicious fire and bankruptcy in 1920 (the Feds were investigating some contract irregularities from WWI). Savage took over shortly thereafter. I was also informed by Researcher that Stevens produced 520s marked as being made by them in 12 bore only. Only Ward's Western Field marked guns and Sear's Ranger marked guns could be had in sub-gauges (16 & 20). Can anyone elaborate on this outline?
