What you're describing, Vern, is the so-called "cross-eyed gun". These are almost always custom jobs made for an individual who has either lost the use of an eye or hand, or where their dominant eye is on the side opposite their dominant hand and so strongly that they need this sort of gun. One of those, a custom Parker, is on display at LL Bean's main store in Freeport. It belonged to the late LL Bean and was made for him when he lost the use of his dominant eye and had to shoot using the other.
It'll be interesting to see the pictures.
