This officer's sword looks very much like my "Le Page"/"Standish Berry"-style sword which predates the CW by a good half century. It would be interesting to know for sure whether it was a photographer's prop or
an heirloom sword pressed into service by a new generation. It does appear he is wearing a sword belt, but the sword does not seem to be suspended from it.

Perhaps I can shed some light on the sword. Certainly not because I am knowledgeable about swords, but simply because I am researching the regiment in which this gentleman served, know his descendants, and am pretty good at using the search functions for period newspapers.

Obviously, I can't say with 100% certainty that this is the sword described below, but IMHO, the Captain would have been pretty proud to have the sword and would likely have wanted his picture taken with it.
Presentation of a Sword to the Oconee Volunteers
Gen C. F. Hardy presented Capt. Thompson of the Oconee Volunteers [became Co. G of the 16th GA] of Jackson county, with the sword worn by his father in the service of the country during the late war with England. The following were his remarks on the occasion:
Captain, Officers and Privates: Gentlemen: I take great pleasure in having the honor of appearing before you for the purpose of delivering to your Captain's care, this sword of my father's, which has been in the earlier age of our country, wielded by him for our liberties and the freedom of our common country.
Reposing a like faith in the valor and fidelity of your captain and yourselves, I shall commit this sword to your care, for the purpose of driving back the invaders of our soil – those who without cause are attempting to subjugate us and deprive us of our liberties. I know of no person who is more worthy, more able or more willing to wield this sword to the perpetuation of those liberties which it once assisted to achieve, and to the honor of him who first wielded it, and to the honor and glory of his country's cause than your captain.
Capt. Thompson, thus believing, I commit this sword to your charge, that should you come in close contact with the foe, the invaders of our soil, you will not permit it to return bloodless to its scabbard; thereby showing to our foes that come weal or come woe, you are determined, by the assistance of your God and the God of our fathers, to sustain that liberty so dearly won by them, and to have our constitutional rights or die in the struggle for them.
Captain, Officers and Soldiers: In parting with you, I commit you to the care and keeping of that God who is so able to take care of you, though bullets may fly thick around you. May His arm uphold you, and His Almighty arm sustain, shield and strengthen you, and may He preserve you all and return you safe to the embraces of your families and friends. [end of article] Southern Watchman (Athens, Georgia), Jul. 31, 1861, page 3.
The family does not have the sword. Thompson was severely wounded and captured at Crampton's Gap Sept 14, 1862. He was furloughed and disabled from further service. The family does not know if he had the sword when he returned home and gave it back the Hardy family OR if it was retained when he was released.
