What astonishing groups of medals, Chris.
They are absolutely amazing in every respect!
I suppose that if it was possible to find an American counterpart, it would be a group that included a Southern Cross of Honor, awarded to a former Confederate soldier of the Civil War, along with his United States Army Campaign medal for the Indian Wars or the Spanish American War, reflecting that the former Confederate went on to serve in the United States Army with his former adversaries.
I know that there were indeed such men, but I have never seen a group such as I've described.
The groups that you have posted are, without doubt, some of the most fascinating and historically significant that I have ever seen (and, without trying to sound self-important, over more than 40 years of collecting I have seen A LOT of groups!).
