Double barrel matchlock shotgun

The Double barrel flintlock shotgun is in my opinion, one of the most elegant looking guns.

But, was it born in the flintlock era?

I have seen pictures of double barrel matchlock pistols, but not a shotgun.

Were there any double barrel matchlock shotguns made?

Clyde,

I can not think of any.
There were reveolving matchlock long-guns, and the Hermitage Museum has a few outstanding examples.
These worked like a regular revolver, but I think turned by hand and locked into position by a spring.
There were also multi-barreled matchlocks, one I can think of with barrels pointing in Both directions!
This is more on the Landsknechts harquebus principle, but with short barrels as well as long.

Cannot think of any doubles though, but never say never!
The flintlock remained a single barrel (In most cases) until the mid 18th C, so I really believe that the double was a result of later developments , and nothing to do with the matchlock.
Super-imposed matchlocks were used, just never seen a double in the normal sense.

The reason s x s doubles did not come along every early is they had not learned to regulate the barrels so that each barrel would hit the target.
