Flank or Yeomanry Officers Sword with Shamshir Blade

[sabertasche]

Reaching out to the Hive mind on a sword I picked up this yesterday. I have posted this on the FB page but thought that there are many who do not use social media.

At the gun show, initially I saw a British Yeomanry or Flank officers’ sword, circa 1780 – 1800. The guard is white metal (nickel-silver), brass pommel & strap, ivory handle but the blade is an indo-persian shamshir! The blade has a definite pattern too it, the picture I've posted just hints at the pattern. I plan to very gently clean off the dried oil, nicotine and gunk to get a better idea as to the pattern.

I’m now thinking a composite sword, note how the guard fits the pommel and how the hilt has been peened to make it tight to the blade. Note that the ivory handle does quite fit the ferrule. Clearly, this sword was put together over 200 years ago but is this normal for Yeomanry/Flank swords to be non-standard or bespoke? There have been some interesting ideas on-line that this is a trophy sword but what does the Forum think?
