BY JOHANN WILHELM KEIBEL (FL. 1788-1862), MAKER'S MARK ONLY, ST PETERSBURG, CIRCA 1830/1840, THE FLANGE STRUCK 631

Johann Wilhelm Keibel was the son and apprentice of the famous goldsmith Otto Samuel Keibel. After his father's death in 1809, he adopted the same mark and became master in 1812. In 1828, he reworked the Imperial Russian Crown for the coronation of Tsar Nicholas I. Keibel was the most important workshop producing gold boxes in Russia in the first half of the 19th Century, but after the death of Johann Wilhelm Keibel, the firm specialised in the production of insignia until 1917.
