This hanger is almost certainly of German origin, probably the Oels family of Brunswick (the hereditary dukes) because of the presence of the gold 'O' featured in four places on the mounts. An unusual feature is the ovoid pommel, similar to that of a smallsword of the period.

This is likely to have been made towards the end of the American Revolutionary War (Peace of Paris, 1783) or during the early part of the Napoleonic Wars (starting 1793). This would have been carried by an RN officer or HEIC naval officer, and this example is interesting in having a particularly long (approx 26") blade.

This is the classic Forestry cutlass worn by senior Foresters (denoted by the ivory grip and the gold/green knot) across Europe from the early 18th century onwards. They continued in use through the Weimar era and Third Reich, only latterly losing the by-knife. Lower ranks wore cutlasses with a stag horn grip and a plain green knot.

This is a classic Ernst Pack dress bayonet, with no maker's mark, but the 'signature' screw bolts which no other maker used. The original owner must have been in a heavy artillery unit, as suggested by the obverse blade etching. These weapons were normally only worn when off duty, but in uniform.

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!
