auld argonian Frighteningly deadly lookin'. There's a small targe-like shield with a flintlock pistol mounted in its center in the Harding Collection of Arms and Armour at the Art Institute of Chicago...in case you needed any ideas for the next one.
There are several like that in the Tower of London colllection
I've seen some using Matchlock pistols and some using flintlock pistols

I also happen to build muzzleloaders
So maybe..................?
