Carl,
You mentioned a quote from the newspaper article. The following is one of two excerpts from Jack Melton's field rtillery:
"3 inch armstrong category:
aguns, U.S. 33; 3-inch wrought-iron guns, banded, rebel, 13;
10-pounder Parrott guns, U. S., 10; 20-pounder Parrott guns, U.S.,
2; Coehorn mortars, rebel, 1; 3-inch Whitworth guns, rebel, 1;
12-pounder howitzers, U. S., 5; 12-pounder howitzers, rebel, 3;
3.4-inch Blakely guns, 1; 3.67-inch rebel guns, banded, 1; 3.80-inch
smooth-bore guns, 2; 24-pounder howitzers, U. S., 4; 24-pounder
howitzers, rebel, 2; 24-pounder howitzers, U. S., Dahlgren, Navy, 1;
12-pounder Armstrong guns, rifled, rebel, 5; 12-pounder iron guns,
re-enforced, rebel, 1. Total number, 251. Rifles and muskets, 21,177;
carbines, 1,293; pistols, 163. Total number small-arms, 22,633.*"
so I guess Sir Armstrong disregarded the British policy of not selling to the Americas.
