That's some very cool family history!!!What I posted I got from Elmer Kieth books described to him as a young man by actual civil war cavalry vets. They used and preferred revolvers, Spencer carbines and sabers ! My great great grand dad used a Sharps paper cartridge carbine, a saber and pistol would have completed his issue armament . We still have the Sharps in the family which he most likely would have purchased personally.
