Thanks Bob, lots of great color pix and very good articles about cannons and other weapons. I don't even think you could buy a book with such excellent photos of some of those priceless, elaborate weapons. I've recommended that the other members of the Company of Military Historians have a look. I'm sure you know CMH Fellow and officer Rene Chartrand, who is pictured in the second edition at a conference in Rio. As we used to say "tough duty but someone's gotta do it."
I'm trying to ID a small bronze howitzer so I'll post a link to my video of it and ask your assistance shortly, in a new discussion.
