After been reading a lot of these old guncatalogs from all kinds of british gunmakers, it appears that the Gaugegun was more or less faded out just prior to WW1. The Henry Jones underlever and rebounding hammers was "vogue" from about 1875-1900 where the hammerless more or less took leadership...but yet, a conservative Gent of 1912s england could still had a gaugerifle ordered to fit with all features of yesteryear. The price difference from a Holland & Holland hammerrifle "best quality" to hammerless "royal grade" was approx 20 Guineas(1904).

Here is my question: If anyone here knows that there has been double gaugerifles(not paradox) made after WW1, I would like to know....
