Hawg: My '51 is bought second-hand from a fellow on this forum from back east, whose (father? grandfather? It's been awhile and I can't remember now...) used it for years in Civil War re-enactments. It's plenty broke in, and looks like it (no disrespect intended to the seller... he advertised it accurately). It's possible the wedge is over-broke in, it is visibly peened.
Perhaps a new wedge and arbor would make it smoother to remove.
