Several years ago, my friend Joe Lozen had an opportunity to fire an original Hotchkiss Revolving Cannon. He kindly sent me this clip – it is the only footage of one of these actually firing live ammunition (note the recoil) that I am aware of. Thanks, Joe!
You can also see some video of US military drill and blank firing from the Fields of Thunder Museum here:
These cannons have a cluster of 5 barrels that rotate, chambered for 37mm (1.5″) shells. For more information on the design and history, see my full video:
I remember watching some “B” movie when I was a lad – I think maybe in some kind of “steampunk” setting – that featured a vehicle that fired a multi-barrelled cannon, and I’d kind of mocked it because “that’s not how Gatling guns work”. Apparently, though, someone in their prop department knew that, and was either using, or trying to replicate, a Hotchkiss gun.
A Hotchkiss revolver cannon relies more upon projectile payload than it does upon sheer volume of fire alone.
An A movie when it was new:

I’m pretty sure the movie I’m thinking of was ’70s vintage. And from the trailer (hard to imagine how I lived all those Saturday afternoons without seeing the film), seems to carry a conventional Gatling.
The world needs a Hotchkiss replica.
There are many ways to classify a revolver, but one is often interested in the classification according to the ruler or the shape to distinguish.
