My sister drove back from my parents' house in South Carolina today and brought my dedicated 10-inch ball and tongs. They are now in their intended spot as the "capstone" of my cannon ball pyramid.
Dedication plaque:
Markings on the very nice foundational balls:
1) Star for Charleston or Columbia Arsenal on another 10-inch mortar ball:
2) Another star peaking out on a 10-inch Columbiad:
3) "D" believed to be for the Atlanta Arsenal:
Full view of the tongs. Note folks that real cannon ball tongs don't have pointed ends like the ones used to haul ice or logs do
I may have to talk to a certain someone about getting the balls for another layer...
