The hilt could be Dutch or French, the use of tortoiseshell having been introduced to Europe in the late 17th century, probably through Dutch colonial connections. The mid 18th-century German blade (26" long) would have replaced an earlier, shorter, straight, double-edged blade (broken?), probably to enable the weapon's use as a naval hanger.

These dirks would have been carried by Royal Navy as well as merchant marine officers, even, rather more rarely, by army officers. This classic dirk has a whalebone haft (which, at first glance, might appear to be of walrus ivory, but on closer inspection is definitely whale bone) and iron mounts. The style of hilt, pommel and grip dates it.

This is the bayonet for the .451 muzzle-loading Whitworth rifle. In extensive trials these were issued in 1863-67 to infantry units, including various guards and rifle regiments. Some 8,000 bayonets were produced, the general scale of issue being some 68 rifles and bayonets per regiment. The 2nd Battalion 60th were in the Maori Wars 1860-70.

This is a senior administrative officer's sword, probably either a surgeon or an apothecary, viz the twin-headed serpent on the guard. The little dolphin head at the end of the knuckle bow by the pommel indicates the naval branch of service. The mounts are ormolu and the grip is ebony.

This hanger, almost certainly of military or naval origin, is an exceptionally clean example with a 24" sawback blade and a staghorn grip. Typically they would have been used in the Seven Years War, as well as in the US War of Independence. It would have been carried in a brass-mounted leather scabbard, now sadly lacking.
