1822 British Lancer Mameluke

[Richard G]

I would like to further expand Bryce's point that mamelukes were not restricted to Lancer regiments. They were also not restricted to the army, or military in general. They were, and still are, in common use by civilians when in uniform. Thus British Governor Generals, Lieutenant Governors, Lord Lieutenants etc. when 'suited and booted' would all typically carry a mameluke. When you remember the extent of the British Empire you realise there were a fair few of these. Even now senior diplomatic staff carry a sword (generally a court or small sword), but also possibly mamelukes in the past. When you consider that prior to independence there were 584 Princeley States in the British Raj in India, each having a British Political Officer and probably staff you can conceive there must have been a market of sorts for such swords.
As this sword has no markings and no indications of military origins I wouldn't rule out it being a civilian sword.
Best wishes

PS. If British, I would generally expect to see a cutler's name on the locket. But I am sure exceptions do exist.
