some prop shops can repair it but…. it is old and they may or may not have what it takes.
ask around
seems I saw a solution some time ago …drill a hole (off center) across the prop body and hub and insert a pin or screw to lock hub and prop together. 2 likely need to balance the prop !
change the propeller shaft drive pin for a brass pin because you will no longer have hub slipping to protect the prop shaft and gears
