Revolver Gun Christmas Ornament

I've done as much searching on the Internet as I can and still can't satisfy my curiosity about this old 'Christmas' Ornament. Has anybody seen anything like this before? I imagine the only reason it survived in such good condition in my parent's things all these years is because it was boxed away and nobody really wanted it on the tree... But at some point they either bought it or received it; maybe it was part of a package deal? Who knows? It's very lightweight, made of glass. Looks hand blown to me, but must have also had some type of a mold to create the shape and lines on both sides. Paint is darker at the top where the metal (lead?) hanger is.
