Wonderful antique large silver serving fork. 
Nautical motif - three dimensional ship at the top of the handle. 
Super nice realistic details.
European, probably german, circa 19th century.
Marked with silver hallmarks. Guaranteed solid silver, 800/1000 continental silver standard (lower than sterling).
Good original antique condition with minor indication of age - some very light normal scratches. 
No repairs.
About 10 5/8 in. (27 cm) long.
About 4.6 troy oz. (145 grams) - very heavy for the size!
