All the shot so far recovered is of 78 – 80 mm (3? inches) diameter which reinforces our current view that the guns are all the same, that is to say 7 foot long, cast iron, smooth bore, muzzle loaders of 3½ inch bore and 14 hundredweight (1568 lbs)I tried my empiracle calculations and I would have said that I would expect 4 pound shot, for the shot diameter and the gun weight. My first idea was that it would be a Falcon, firing 3-1/2 pound shot. I have trouble believing the gun weight of 1568 lbs. For the shot diameter given, that would make for an extremely heavy gun, outside of the range with which I have seen. I concede that for the shot diameter, it must be a Falcon, not a Minion (4pdr). My problem is that the gun weight and length are more like a Dutch 6pdr iron gun. For that small of a shot weight, a similar Dutch gun would be a bit less than a 1000 lbs.
