All three of these marks are identified as those of Jacques-David Muller in François-Pierre de Vevey's Manuel des Orfèvres de Suisse Romande (Fribourg:Sotheby's Office du Livre, 1985), page 30: Maker #96, maker's mark 96-b, city mark 96-B, fineness mark 96-1 (here, struck twice).
The crowned F was used in several cantons as a silver fineness mark: it has been found in Fribourg, Vaud, Neuchâtel, Aargau, Solothurn and Bern. As it was applied by the maker, it varies widely in design. Exactly what it represents is not known, though it probably indicated that the silver was of the Swiss fineness of 11 deniers (.913). This was more commonly expressed by the Roman numerals "XI", though, leading some to speculate the the "F" might represent the higher French standard of 11 deniers, 10 grains (.950).
Muller was a 4th generation silversmith, the great-grandson of Lucerne silversmith Jacob Muller, who was naturalized as a citizen of Fribourg in 1645. de Vevey notes that Jacques-David Muller was captain of the Fribourg Garde d'État 1752-1782, and was a distinguished silversmith who left behind a number of high-quality pieces noted for their fine construction and elegance.
Nice find!
