DD,
Those are some great shots! They are right in my neighborhood too (about 25 miles).
Have you ever been to the Navy Museum in DC?
They have some great stuff!
We just got some pictures back from there today, but they have to be scaned in.
I have a couple from the digital camera.
This one is a boat howitzer on a mount for a boat.
Another boat howitzer.
This I think is a 12 pound Brittish, or a 14 pound French?
This is a small portion of the outside display area.
They have dozzens of Bronze guns around a park nearby but still in the Navy Yard Grounds.
You need to call ahead to get in there.
