Montogomery Wards stores did sell Mossbergs back in the day and that is where my dad got his from. Just trying googling single shot bolt action shotgun for a start and click on images to see if there are any like it. My bet would be on a Mossberg Brand. You may want to try Sears store name too. My dad has a .30-30 Sears "Ted Williams" Model that is nothing more than a Winchester Model 94 Lever Action.
