Couple of thoughts on the American market aspect. This Greener was considered a lower half gun of their production range. Box birds seems to have been much more an every man's sport in the U.S. than in the U.K. A moderately priced gun for this market would make sense; particularly a market which Greener was already penetrating successfully with its heavy working guns. Also, in the pre-nitro era, 1 1/4 ounces was the standard 10 bore load. A big Greener, moderately priced, would seem to be a pretty viable option. With the arrival of nitro powders, the 90's saw a real blossoming of guns to support the popularity of box bird shoots. It also meant that relatively light (and thus quick) 12 bores could take on the role of throwing 1 1/4 ounces of 7.5's in a pigeon ring. Thereafter, the old 10 bore hammer guns ended up in attics, duck blinds or the turkey woods.
