Spuddy,
It looks like you found a really nice tube, there, real good looking bronze patina on that tube. Captain Earl is right. He's a lucky fellow to own probably the best looking bronze gun ever made. Perfect lines, perfect proportions. Mike and I saw two long rows of bronze tubes in a bastion blockhouse at Fort Niagara just north of Niagara Falls a couple days ago. There must have been 4 or 5, 6Pdrs. 1841s, 15, 1857 Napoleons with handles and a bunch of bronze 24 Pdr. howitzers and James rifles. It was truly the "mother load" of bronze field artillery!!
We will be looking at 13" bronze mortars and 8" bronze howitzers tomorrow at Ft. Ticonderoga near the north end of Lake George in upstate New York. On Monday we will be exploring Ft. Knox in your wonderful state!
Regards,
Tracy and Mike.
