When did Ruger start putting the long safety warnings on revolver barrels? I was looking at a Gunbroker listing for a Security-Six, and I kept passing it by as it looked like the finish on the barrel was all marred up or worn off. Eventually, I did take a closer look, and the gun was actually in excellent condition. That huge flaw I was seeing was actually the "billboard," which took up most of one side of the barrel.
