In this picture...
... there are 6 guns. All used on the Chesapeake by watermen to harvest waterfowl for market. These put money on the table and food in the pocket. Or vice versa.
The 3 horizontal ones, the one in the middle is the a 12 gauge. The BIG honking ones are punt guns. A 'punt' is the smallish rowboat the duck harvester would mount the beast in. 2 inch barrel, and a pound of shot. The shot may have been made here, at the Baltimore Shot Tower. If the gun didn't shake your boat apart you'd about swamp it adding 50 dead ducks to it. You had to muzzle load em like a cannon. Only thing cooler would be an Italian scooter with a cannon on it.
The 3 vertical pieces are a four barreled contraption, also boat mounted, and 2 double barrel 4 gauge shotguns. I wonder if you could shoot enough ducks to make enough money to get the doctor to fix your shoulder after firing a 4 gauge?
These hunting methods were frowned upon as they devastated the bird population, and soon they were forbidden, but poachers used them up through the 20th Century.

Mike wanted me to see this pic, so he sent it to me
The Missus has a pretty nasty stomache bug - And by "pretty nasty" I'll just elide the details, if you don't mind. But she's up to the toast and seltzer stage, so *Excelsior!*
