Indeed on all counts, except this model (Single Trigger, Double Rifle) retailed higher than the De Luxe. The De Luxe was a slightly curious arrangement of features as many feature the same engraving as this one, and I believe in certain years in the period H&H offered only the De Luxe. Indeed the 1910 catalog only shows the De Luxe, and the Single Trigger. The 1910 catalog prices the Single Trigger shotgun and De Luxe double rifle both at 100 Guineas, the Single Trigger Double Rofle was more. Of course, they would make anything you ordered. By the time this one was optioned out, it was at the top of H&H's price scale. Not that it matters much, every double they made was extraordinary.
As for the bears, I hunt them as half my living (we have an outfitting territory just south of the Alaska border on the North Coast), not too concerned. Would be one of the last great game animals taken with a batch of the stuff. Fresh handloads would be in the other pocket.
