That seven-barrel volley gun is indeed very similar to the Ordnance gun supplied by Nock and appears to have been converted from flint action to the percussion principle via the nipple & drum method. The calibre appears to be the same also, .57 or Pistol Bore. It was most likely for use on a commercial ship.
Goose guns are absolutely a 'thing' and those I have handled have been of smaller calibre. Often the seven bores were drilled out from a single large barrel, rather than a cluster of seven individual barrels, and they will be found with various types of ignition and barrel configuration etc.
