My field of interest has normally been British and Commonwealth arms and I have reference material and a reasonable amount of personal experience with military arms in those categories.  I'm somewhat conversant with US arms but US civil war arms, especially edged weapons, is a field in which I'm very much out of my wheelhouse.  That said, I'm reaching out to this community and requesting help in gathering information and probable evaluation.  At present, these are the only pics I have but more will follow once I actually pick up the sword.  I'm aware of both the reproductions and the fakes made with intent to deceive and I've been stung a couple of times during my learning curve.  I've not seen Pakistani, Chinese, or European fakes made with this attention to detail and particularly with the proper shagreen grips.  Any observations, information, or knowledgeable input would be most appreciated.

It's correct. Virtually identical to the example shown in Thillmann's book "Civil War Cavalry & Artillery Sabers". As he mentions, the Horster cavalry officer sabers, unlike most of the German  imports, have a French style embellishment on the quillion. My 1840 import was also missing the wire, but I picked up tarnished brass wire from Tom Nardi's Sword Restoration for an inexpensive rewrap. Directions were included. Thillmann also says the Horster officer sabers are seldom encountered.

Thank you!  Sadly, I was conned in a classic "bait & switch".  The seller had this sword up for a ridiculously low price.  Though my spidey senses were tingling, there was the possibility that it was low priced due to ignorance.  I've gotten incredible scores like that in the past.  As it turns out, this was a "sold' item, according to the seller who just happened to have a load of cheap Chinese and Pakistani garbage blades for sale, if I wanted to see them instead.
