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.

This iron-mounted sabre, dating from the early years of the Napoleonic Wars, would have been carried by a British officer in a cavalry or yeomanry unit. Singularly, it has a backstrap/pommel in the form of a lion's head, something I have never seen on this pattern in over 50 years of arms dealing. All I need is a good portrait to pin it down!
