Questions.. 1816 Harpers Ferry Musket 1833 dated...In what manner was the ramrod retained? I see no pinned spring retainer or threaded hole in the trigger guard plate or bow for one...Was it a friction fit into the wood? Or...Did it thread directly into the wood? If so...Was the thread form like a wood screw or like a regular machine screw? If like a machine screw ...What is the approximate thread pitch? Or did it thread into some kind of metallic receptacle embedded into the wood at the end of the ramrod channel? If so what is the approximate thread pitch of the ramrod?
