I’ve just taken in a musketoon with a smoothbore barrel, the stock has the Parker hale roundel but the barrel has no markings whatsoever, the barrel is blocked with a steel bar but doesn’t look like a deactivated version. Has anyone seen an inert musketoon sold by Parker hale? The lock functions & the nipple is as normal. It may have been a model but because there are no makers marks on the barrel & the bluing isn’t the normal standard, I’m at a loss as to whether it has ever shot or was it sold as inert originally. Anyone know of these or ever seen one?
