I believe it is Artillery Officer's but may be Cav.
Most likely early 1800's.For sure US but don't know if foreign made as no markings.
Looking from blade side the cross guard has a flaming bomb in it.
Blade is not the greatest and hard to photograph but has floral designs and crossed flags with drums and cap of freedom on it, other about the same but has Federal eagle and motto.
I just love these early 1800 swords. What do you think?
