Cal,
I enjoy your photos. If you are ever in Oklahoma City, there is the 45th Infantry Division Museum near NE 36th and Martin Luther King Blvd. While most of their displays are of Army artifacts, they do have some aircraft in their outside displays. Inside are lots of firearms dating back to flintlocks and cap and ball weapons.
Here is a link to my Smugmug website where I've posted a bunch of photos taken at the 45th Infantry Museum.
