No one that has seen them has seen a dead letter CDV and a non dead letter of the same CDV. This is a quite unique opportunity to get something that no one else has. Sadly the soldier in the CDV has not been able to be identified.
One of them has the name "Argus Ogborn", from my understanding he was a big CDV collector. Ironically both these turned up out of New York. This is really a great pair.
