Some 400 of his cannons were produced, most made of iron. Blakely also sold some to Russia and apparently, the state of Massachusetts bought an eight 9-inch and four 11-inch ones.
He continued to experiment with designs and had at least five and possibly as many as ten different designs with several varieties each. There were at least nine varieties of the 3.5-inch, 12-pdr rifles (I believe the one in Raleigh is one of these).
The two primary rifling types used appears to be flat-sided bores or bores with grooves cut in them into which flanges on shells would fit.
Variations included:
2.5-inch, 6-pdrs (length and weight)
2.9-inch
3.5-inch, 12-pdr.
3.75-inch, 16-pdr.
4-inch, 18-pdr.
4.5-inch, 20-pdr.
6.4-inch, 100-pdr.
and larger models.
