Many thanks indeed for the input on this sword. Its very pleasing to know its probably such an interesting and historic piece.
So, presumably at the time of the American Revolution - the colonists lacked arms factories and blacksmiths were pressed into service making weapons... ?
I didn't mention that the blade is double-edged and of shallow diamond section.
Thanks to Mark for the references - I will pursue these.
Any recommendations about cleaning, or maybe its best to leave it as it is for the present ?
Regards
