1780's Brit/Irish/American? cavalry sword

[Hotspur]

Glen, I was hoping you might enter in here, as when it comes to swords in these fields, your knowledge and expertise are well known in these forums. Thank you for linking the 2002 discussions. I am always happy to see old threads revived and 'cold cases' revisited, as often new evidence and examples can be brought together with the older material.

The thread I linked is the 2015 thread. As far as I know, there was no thread of Will's from 2002. Many of us have been around since then but Will introduced the sword last year (afaik).

Cheers
