Hi - sorry to be late to the party, but I hadn't spotted this thread before. Just looked through all of your photos and it was a splendid effort - and I say that as the person who wrote the Spencer's Ordinary scenario for the British Grenadier scenario books.
I was also one of a group of wargamers who put the game on at the National Army Museum in London one weekend about 15 years ago. We were joined by an unusually large group of American tourists, who had decided to wander through the Portrait Gallery (now sadly "updated" - ie removed) and were amazed to find something replicating their own history. We found some chairs and got them all seated around the table, while I explained to them that virtually every person on the real battlefield was an American (save for a small company of German jaeger and a few French light infantry officers) and the only man in a red coat was the commander of a company of Loyalist militia cavalry! "The Patriot" (spit!!!) it most certainly wasn't.
