google pepper box traditional revolver,

pepperboxes are multiple bbl. I just googled "improved revolver" and am finding it...multiple similar pieces on a British auction site calling one or more of them them a transitional percussion revolver mid nineteenth century

Look up Pettengill Transitional revolver and you are on the right track. Cheers

Those are Birmingham proof marks. Typical transitional revolver.
