[Cant replace it.]
Horse-pukey. If man made it, man can remake it.
Measure the length & diameter of the original, and make (or have made) a duplicate from either a hardwood dowel or steel drill rod, and tranfer the old/genuine ends/tips to the new rod. If the original end(s) are integral to the shaft of the ramrod, then have the clone softened, swedged to shape/size, and re-hardened.
