Unknown UNKNOWN Muzzleloader Obsolete Rifles

Sorry that I cant answer any technical questions as this was part of a job lot that I purchased and guns are not my speciality. I am listing this as a restoration project as certainly the ramrod is not real. to my eye the gun round the stock area looks very old . The lock pulls to a half cock and full cock position and easily activated by trigger pressure snaps down on the cap area. there is an old number 628 near to the butt and some unusual markings near to which I cannot decipher.. as you see ,the wood has a split on the underside. I imagine this could be an excellent restoration project. The musket is NOT left handed

Looking for sensible offers or will accept some old wind up watches, {not quartz}. The musket must be collected near to the Alton Towers Theme Park Staffordshire.
