We need to see the face of the counterguard. This is a post war fraternal or military association sword, likely of the 1870s but might be a good bit later. The blade was made by Clauberg. The sword was probably sold to the regalia company by Pettibone.
One side of the blades for the commandery or other order and the other side the owner's name. I can dig in some of the books but there is a lot view-able through searches. The regalia and swords sold by them a very minor part of their empire. There are catalogs out there for the 1860s but these are later swords and as mentioned, likely Pettibone imports.
Books to peruse, Bazelon's big book of makers and manufacturers, Bezdek's American Sword Makers; Hamilton, Kaplan and Marino's new testament for fraternal swords.
