Your sword was made prior to the CW by CR Kirschbaum, Solingen Prussia. These swords were imported and were supplied to state and local militia units, and were not Federal inspected and saw extensive use by both sides during the war. Tom does good work but with it being an import and not US made there is no way to tell if it saw service during the CW, therefore I would not wastes the money on having it restored as it will not add all that much value to the piece.
