Colton Manufacturing Co. provided Sears with its first American-made hammerless house brand double. Sears advertised their sidelock hammerless gun as "the equal of any gun made, regardless of price" in their 1900 Fall catalog No. 110. There were four models: three sideplated boxlock-types and a unique unitized coil spring driven striker assembly version. All these, especially the latter, were designed to be mass produced. Many of the distinctive sidelock-within-a-sideplated model were produced but they are seldom seen today either because they were used-up or did not hold up well and were scrapped. Sears replaced Colton with the more traditional design Fryberg gun in 1902. Values depend on grade. There appears to be at least two levels of quality and condition ranging from $300 to $1,500. Colton-marked guns are scarce.
