Organ Guns

Does anyone know of any period depictions of ribauldequins or organ guns from the 14/15th centuries? I have a couple drawings even some photos of a working model of DaVinci's design, but I'm having trouble finding any other pictures in manuscripts or engravings from the era.

I'm planning on reproducing one of my own, and while DaVinci's designs are very interesting, they tend to be somewhat elaborate. I'm looking for something simpler. Does anyone have any information they can share with me?

There is a museum in Vermont ( The Sherboune Museum), In there collection they had a simalar gun on display, the one they had was used by market hunters on waterfowl, i believe it had 10 barrels of .75 caliber. I dont know if any pictures are available. These guns look pretty simple to build.

Thanks. I'll have to check that out sometime.

Yes, they do seem pretty simple. I'm more so just concerned with the different carriages they were mounted on. I've seen modern illustrations of them with spears pointing forward or hinged pavise shields on the front. I just want a primary source or two from the 14th and 15th centuries to go off of (if they exist!).

The DaVinci ones I spoke of are neat, in that one has all the barrels at slightly different angles, like a duckfoot pistol, then the other has 30 barrels mounted on a rotating platform. It allows 10 to be fired while the next ten in line are being loaded. Really neat idea, though I doubt I would want to be loading just a few inches from the touch hole of a firing gonne!

Got a reference to a pic of one of these things? Personally, never heard of it-sounds like the original Gatling gun! Imagine a chain fire!

Good ole wiki:

Widget's response has it. Its the one on the left. You see how it would rotate every 10 or so into firing position.

A chain fire is what it is designed to do, it has a single ignition point and as the first barrel in the line fires, the other barrels have linked touchholes, the flame of ignition travels from one to the next untill all have fired. I built an exparimental model with 6 barrels, they fired so fast that it was like one long shot going off.Many of the originals had 2 rows of barrels on each level and rotated with 3 sides. definatly the first of the (gatling concept)High volumes of fire usualy won the battle.

Leonardo copied a lot of his military ideas from Konrad Keyser who wrote a book called "Bellifortis" about 70 years before he was born.
I've seen a reproduction of his manuscript in the State Library rare book collection and he has an organ gun and several revolving cannons in it...
shouldn't be hard to track down on the web
