This is an Austrian pattern, which was adopted by the British army in 1796 as a dress sword for Heavy Cavalry general officers and militia units. It would have been used throughout the Peninsula War and at Waterloo and beyond until about 1820 or so.

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!
