Poor's brigade had a section of grasshopper guns at Saratoga. I'll be using this butterfly gun instead.
I painted the gunners in matching uniforms for two reasons. First, since all the combatants' artillery uniforms were so similar, a uniformed crew can be used as British or Hessian gunners if a scenario requires. Second, I was just sick of painting an ill-uniformed rabble. It takes a lot of time to make a unit look sloppy, but it's easy as pie to make a unit look uniform.
