Hoping someone can provide more info on the revolver in the pics below. The R.J. Braverman Stinger Pen Gun (not NFA) isn`t all that rare, you see them for sale now and then. But the revolver is a mystery (at least to me) Five shot double action only top break. Fires from bottom chamber of cylinder. Folds into its own grip. 32acp. Has a manual safety. (yes, a revolver with a manual safety) Probably made in the early to mid 90s. My best guess is that it is one of a few tool room samples built for testing, but that the gun was never commercially produced.
