HOF-BUCHSENMACHER/Sr. MAJESTAT DESKONIGS v PREUSSEN" in gold inlay on the top straps of the frame and "Sr. MAJESTAT des KAISERS v. RUSSLAND." on top of the barrel. These gold inlaid markings translate to "H. Barella Court Gunmaker/His Majesty the King of Prussia" and "His Majesty the Emperor of Russia".
