I've recently done a series of commissions for an upcoming tabletop miniature game called "Imperial Skies" which will utilize the "aeronef" range from Brigade Models, mating it with an all new ruleset.
This is the forward turret of the "HMS Camperdown", a "Benbow class" flying ship. I've chosen the name Camperdown in reference to the ship which, in real life, was Benbow's fellow of the "Admiral class" and which collided with and sunk "HMS Victoria", Vice-Admiral Sir George Tryon's flagship during manoeuvres off the coast of Tripoli, in modern day Lebanon.
Since I had to follow an existing design with a very shallow hull I had trouble adapting a regular barbette design, so in the end I went for a cross between a turret from the American monitor "USS Monterey", the real life Camperdown's barbette and a fortification turret.
Also, since the ship is airborne, I added a bottom armour plate which does not exist in regular, "wet-navy" ships.
