The general pattern of this sword is the gladius. In the 1830's, this sword pattern became popular again with the French infantry swords and also the m1830 U.S. artillary swords. After those patterns, there were a series of ceremonial types that resembled this patterning. I believe that's what you have here, roughly the same time period cs 1830's-50's. It should be noted that there were American Confederate swords with this pattern as well, BUT I don't think this is one. I've never seen one with a criss-cross hilt pattern like this. Most have brass with same crossguard, but simple spiral grips...
