Quiet Street Antiques of Bath has dated this piece to the 1860s.
In relatively untouched and unrestored condition, the quality of these pistols (probably target, though perhaps duelling?) is stunning, with beautifully carved ebony half-stocks; superb engraving to the side plates; engraved spur trigger guards and rifled blued steel barrels. Both pistols are fully signed.

Gastinne Renette (from about 1839 to 1890) is considered one of the finest French gunmakers, appreciated as much for technical and innovative skills as well as artistic flare. The firm made pieces for many aristocratic families in Europe and France including Emperor Napoleon.
