The distinguishing feature of the Savage built Fox-Sterlingworths with the "drawbolt" is the wide top tang with big screw head and kind of a notch in the profiling on the sides of the receiver just below the watertable --











To date, all the observed "drawbolt" Fox-Sterlingworths have been 12-gauges. The first batch is a bunch in the 133xxx serial number range, to date all observed with 30 inch barrels. Then another bunch in the upper 143xxx range with both 28- and 30-inch barrels, and finally a batch right at the end including the one shown, in the 1615xx range with 26-inch barrels. While most of the "Drawbolts" observed are double trigger plain extractor, a few have been observed with ejectors and one with both ejectors and a Fox-Kautzky single selective trigger.
