I have a seller who has a stunt rubber weapon prop that I have interest in buying. He says it was used by the actor to practice getting use to holding the real weapon and for any aggressive scenes where the actor might get injured. My question is, how can one tell if this was actually used by the actor or instead used by the stunt person? Do these usually have some indication written or etched somewhere that one is made for the actor to use vs. the stunt double? Thanks!
