The basic Sea Service pattern was used from the mid-18th century into the early 19th century by the Royal Navy around the globe including during the French & Indian War, American Revolution, War of 1812, and Napoleonic Wars. The Tower lock bears a clear royal cipher and "crown/broad arrow" mark. "I-B" is carved in the wood just ahead of the trigger guard.

Very good, showing mostly a mottled dark grey patina with some areas of mild pitting and varnish, clear markings, and an aged patina on the brass. The revarnished wood is good with minor dings throughout and some chipping around the lock.
