I just noted a apparent defect/repair in the rapier (cropped pic below) where one of the sidebars joins the cross guard. Is the light substance brass (as in a brazed repair) or some sort of adhesive? A brazed repair would be more indicative of a 'user' rather than a wall hanger. Adhesive (epoxy?) would mean a modern botch job. Same if it is a recent tig or spot weld that hasn't been smoothed & matched in patina...
