GGaslill,
Very interesting! What issue of the MCH did the "further notes" come out of? I had read the earlier articles but the info in the further notes in news to me.
Based on the evidence presented about the work location of Daniel King and the other notes about the Howitzers and Petronos (sic) he was making during the Rev War, I'm not totally convinced that what he was making then is the same howitzers that we know he made in the 1790s. However the other research does proves to me that some style of brass and iron 3pdr howitzers were being used. "four 3-inch Howitzers, 1060 shells, 200 grape shot, 200 canister shot, 200 "Round Cartridges," 200 tubes, and 1068 fuses." That quote is pretty convincing to me.
Opens up a whole bunch of possibilities!
