    No further details. It came up on my Pinterest feed, and people on there are notorious for mangling information.

    Although it is interesting to look at I don't know that posting a picture of it without any information about it serves much purpose.

    "repel all boarders!" I like it. Looks like an early breech-loading 16th/17th century type with the barrel construction like that. I hope it is functional, but given the potential liability issues from gasses escaping at the breech, I it may not be. As above, any details?

    Greener has a picture of a similar breech system in his book and IIRC says it was 14th century. There was a show about such cannons on TV a few years back. The Englishman talking about the design called the breech a thunder cup, (not mug.) and he fired one that was a bit more primitive.

    It’s of a type used on King Henry 8th’s ship Mary Rose. I have a friend who has made a couple of replicas. As long as the wedge is in tight, there aren’t too many problems with escaping gases.

    They were called barrels as they were made from slats held with those bands shrunk on. They were fired with serpentine powder. Could it hold corned powder?

    One will note the reinforcement timber "knees" behind the railing where the pintle is installed for the swivel gun. Needed for recoil!

    For those who don't speak Spanish:
    1. Barrel, 73mm caliber, made in bronze or iron, with an approximate weight of 95 kg. [In the American Revolution, a swivel gun weight over 150lbs., but a "wall gun" with a smooth bore weighted about 50 pounds, albeit subject to considerable variance.]
    2. Breech, area where the interchangeable firing chambers loaded with powder and shot were placed.
    3. Stone ball of 1 pound/ approx. 400 grams.
    4. Wooden shoe/sabot or tampion to fix projectile within the chamber.
    5. The interchangeable firing chamber, a unit containing the powder and shot. Several shots for the piece could be prepared and held in readiness.
    6. Vent or touch-hole for firing the charge. ...
    10. Tiller for aiming the piece.
    11. Wedge for fixing the charge/ interchangeable firing chamber into the breech.

    It could certainly HOLD corned powder, but it would probably blow up as soon as it was lit.

    I think the old breech loaders were abandoned when corned powder came along because they couldn't handle the increased pressure until metallurgy caught up.

    How late did breech-loading swivels last among European/western nations?

    You say replica in title. If it's so then by definition it is non firing show piece.
    If a reproduction then it is capable of use. As I understand the defines of the terms.
    Only point this out because stated , hope it functions.

    Bang. Your being just a little pedantic . Ime sure most except Replica means fireable if it cant then its a prop . Such a piece if well wrought should fire OK, might be a bit of gas escape whats that on the scale of things ? ' Mons Meg' did burst took the King with it maybe the stone ball stuck a bit who knows , We all have off days Did fire a replica of Puckles 'Machine gun" slow as old Nick but interesting Regards Rudyard
