Produced in response to a request from Sears Roebuck, that Marlin should manufacture an over/under shotgun for Sears to market in their stores. Guns produced for Sears have prefix 103 in their serial numbers and marked "Ranger" before WWII and "J.C. Higgins" after the war. Prior to 1945, they were not marked Marlin; after that date Sears requested that the company stamp their name on the guns. They were also produced as Marlin Model 90 during the same period. Chambered for 12-, 16- and 20-gauge, as well as .410 bore. The 16- and 20-gauge guns first offered in 1937, with 26" or 28" barrels. In 1939, .410 bore was first offered with 26" barrel and 3" chambers. Barrels are 26", 28" or 30", with various chokes. Action is boxlock with extractors. Guns made prior to 1950 were solid between the barrels; after that date there was a space between barrels. Can be found with double-/single triggers and checkered walnut stock. Ventilated rib offered as an option beginning in 1949. Be aware that this model was also available as a combination gun in .22 LR/.410, .22 Hornet/.410 and .218 Bee/.410. Approximately 34,000 Model 90s manufactured between 1937 and 1963. NOTE: Add 33 percent single trigger; 25 percent 20-gauge; 300 percent .410 bores; 300 percent premium combination guns. There are other rare gauge and barrel combinations that may affect value.
