There seems to be a misunderstanding of the guns that we need. All we need now is the crossed shotguns in the background. The crossed guns need to be the skeleton of over under shotguns. It has that "Pirates of the Caribbean" look and feel which i really like. If there is a go-between for the two shotguns, that would be great.
Here is what an over under shotgun looks like. See link below.
