Thanks for coming in on this one, Jim! I was also wondering if it might be earlier than my assumption of ca. 1700, as I know there were earlier hanger patterns. You also concurred with it being possibly maritime, possibly infantry. Maritime swords had the uniqueness of all manner of nuances, like this twisting brass blade. I've even seen a naval hanger with a pewter grip before! Always the odd ones and that's why i love them!
