I saw this model in an online version of a 1910 catalog. It cost 45 guineas when the Royal model cost 75.

Is it a "Best" quality gun with plain border engraving? Like the "Gold Model" Westley Richards that has no engraving yet was built to "Best" gun standards?

If it isn't, how does it differ? Are the barrels not as good? Lock works not as well done?
