Jim, it appears you have a long way to go to untangle this knot. Like the virtual COME AND TAKE IT cannon is not that small piece arguably called esmeril
* but a six pounder which, according to
period parameters, should measure 66 inches, weighing some 750 pounds, with a 3,5 " bore. To the extent that the COME AND TAKE IT piece exhibited in the
Gonzales museum is the other vpiece of the puzzle.

As established, the esmeril is completely another thing, a breach loader with a distinct (slimmer) shape. Notwithstanging such 'practical' name attributed may not be serious obstacle; only a detail to help confusing things.
