Thought I'd add my two cents (or maybe a tuppenny).
Interesting, I shall attempt to add a thought on the mix and matching world then. What a mess the sword mfg. was in at the end of the 18c! England over-extended on three fronts, adoption of a set 1796 pattern for swords was imposed to replace the mess to try to sort out all the variations into a more uniform mess, to increase supply which was falling behind, at least for troopers and ground pounders, Navy and officers came later. Officers had a wide leeway in selecting their swords, as they were and are still never 'issued' but bought privately.n Even std. Post 1796 blades varied amongst officers, as long as the hilts looked vaguely true to the patterns from a distance.
My 'American' revolutionary sword was originally a French dragoon sword, had part of it's brass 'basket' removed, possibly due to damage, in the transition to American service. British Royalist/Royal Dragoon swords were also made by Pooley or Pussey (sp?) in New York based on English 4-slot designs but a round grip and a urn pommel. You see replicas in the Mel Gibson film used by the wicked UK Dragoon leader. The film history is suspect, but the swords were fairly correct.
Mine was discussed
HERE a while back and may be a naval variant. Oh what a tangled web we weave, etc.
