I stumbled across a website called www.histandard.info which has all kinds of information about guns manufactured by High Standard. Sears had a long-standing relationship with High Standard and marketed a number of High Standard-produced guns under the Sears or J.C. Higgins name. One of those made by High Standard for Sears was the J.C. Higgins Model 52, a .222 built on a Sako L-46 action. The rifle was well-finished with a walnut stock, generous hand checkering, and a 26-inch mid-weight barrel. The histandard.info website has a chart showing that the Model 52 was first offered by Sears in mid-1955 and was last offered in mid-1959. There is no information to show how many Model 52's were produced, but it does show that their serial numbers ranged from rather low to rather high in the L-46 series. I'm still trying to determine if High Standard, which was located virtually across the street from Colt, was the maker of some of Colt's early Colt-Sako rifles, as well as perhaps the Montgomery Ward L-57 WesternField rifles in .243 and .308.
