To complicate things, some few HE Grade Super Foxes were made on the standard 12 gauge SIZE frame that measures 2.340-2.350" across the breech balls/fences. In comparison, the heavy 0-size frame will measure about 2.420".
One such standard frame Super I own, was "ordered light" and it left the factory at 8 pounds, 4 ounces. And it does have the regular HE frame engraving, and the later-era Super Fox bores at .738". The record card for this gun shows it as an HE.
Regarding the gun in question here, I agree it may be outside the typical HE grade/Super Fox parameters. Just two observations for whatever they're worth: the H stamp on the barrel flats is not the usual special font, and its 3" stamping is also atypical. IMHO. Silvers
