The principal figures found within the decorated steel and silver elements of this gun are possibly representations of Duke Ernst August II and his wife, the celebrated Anna Amelia of Brunswick-Wolfenbüttel, whom he married in 1756.
The carved designs on the stock compare closely with a plate signed De La Collombe included in the series of plates published by Claude Simonin in 1705, and a further edition in 1730.
The barrel forger's mark 'FG' is also found on the barrel of a gun of the Suhl school in the Wallace Collection (A1119), made for either of the Dukes Ernst August of Saxe-Weimar.
For a detailed account of firearms of the Suhl school and in particular of those attributed to the Stockmar family, see The Wallace Collection Catalogues, European Arms and Armour vol.II, 1962 and Supplement, 1986.
