There have been over the years numerous very low volume, obscure Spanish gunmakers. Your revolver has is likely the product of one of these, but it is unlikely that anyone will ever be able to identify just which one. I would think it probable that it was imported into the U.S. sometime during the inter-war years. Sorry I can't be of more help.
