Similar to early A Grade and offered in 12- and 20-gauge. Chambers were 2.25" standard, with 3" chambers available on request. Marked on the barrel "Not Warranted". This referred to pattern density, not barrel quality. Only sixty 20-gauge HE Grades appear in factory records. Manufactured from 1923 to 1942. NOTE: Add 20 percent for single-selective trigger; 100 percent premium for 20-gauge.
