When first introduced, the SP-/SPE-Grade was very plain --



In 1934 Savage showed the Fox-Special Skeet Grade in the illustrated Wholesale Price List --



Then in 1935, they introduced the SP-/SPE-Grade Skeet & Upland Game Gun, a much nicer stocked and finished gun --









About this same time the regular SP-/SPE-Grades began appearing with the bit of border engraving and stippling as the gun in question.
