I disagree concerning Ruger's lack of market research re: the Gold Label. In 1976, I met Bill Ruger at the annual National Sporting Goods Show in Chicago. We had a discussion about doubles and specifically the Dickson round action. I learned that he personally owned a sleeved round action Dickson and admired the design. I wrote Bill a letter following up our meeting about the features that could be considered in a Ruger double, if ever manufactured. I still have a copy of the correspondence. One of his people answered my letter and commented that they felt that the market was not yet ready (1976)for a SXS Ruger. I feel certain that many other people also voiced similar requests.
Ten years later at another major sporting goods show, I learned from one of his people that Mr. Ruger had built a prototype SXS shotgun. I suspect that this eventually evolved into the Gold Label.
