This pistol is a Mannlicher M1899 in 7.65mm. The elaborately engraved and inlaid gun was one of approximately 350 units made for special presentation. This particular gun was made for Kaiser Wilhelm II (1859-1941) while he was still German’s ruler and the King of Prussia. It features extensive engraving and silver inlay on the frame and ivory inserts in the grips, including the Kaiser’s coat of arms.
Another known recipient of this batch of guns included Sultan Abdul Hamid II of Turkey.
The presentation case in the inset photo features a leather lid and is also heavily embellished with colorful paint, gold leaf, and the coat of arms.
