BLUF: No. It is not in Peterson, or Bezdek or other of my sword references. The most visible clue is where the branches of the knuckle bow meet, and I do not see that feature in any photo of any American, Confederate or European sword. It is possible that the sword did not belong to the soldier in the photo, and may have been a photographer's prop. Try to find more details about swords made for export in Solingen, Germany. Enjoy your search for the fact, which is most of the fun of collecting.
