ID SABER PLEASE
 

Hello ,need some info for this saber. Husar?

Morphy auctions has a very similar sword described as American

I would be inclined to go with what Will noted, as the elements of this hilt correspond loosely with European hussar sabers, but seem more rudimentary.
American sword cutlers were producing swords that were basically copies of European forms in the colonies much as British makers were.
I think a check through Neumann (1973) might be helpful.

How old can it be ?

Probably 1770s to 80s, some European examples of these stirrup hilt sabers (with knuckle guard) are earlier but with the look of this, especially the flat pommel cap, likely in this period.

These are British M1788 sabers.

What Jim showed, the British 1788 Pattern Light Cavalry sabre is probably the most frequently-seen example of what I call the "Hussar hilt" sabers. Without the surviving markings they are tough to id 100%, unless an identical marked example surfaces. I have a vaguely-similarly-hilted one in my collection, lack of langets aside...they are, for the lack of better words, cool!
