A very impressive weapon Michael!!!
I would imagine an instant volley from this could startle a charging mass of troops and impede thier advance in theory for a moment. After firing, I wonder how long it would have taken to reload this.
In noticing the barrels, they all seem of the same bore..I have read that the later type guns with standard bore were termed 'calivers' (i.e. caliber), what was the difference between that type gun and the short arquebus noted?
I have noticed the many interesting multiple barrel guns you have posted over time, and though intrigued by them, could not really formulate reasonable questions, but this is a start
All the best,
Jim
