A plaintiff sued a defendant and his employer for personal injuries. The plaintiff claimed that she was struck on the head by a wrench dropped by the defendant from a high scaffold, on which the defendant was working in the course of a construction project. To prove that it was the defendant who dropped the wrench, the plaintiff offers the wrench itself as evidence: The wrench bears the brand name "Craftsman" on the handle, and other evidence shows that the wrenches used by the defendant on the job are "Craftsman" brand wrenches. Is the wrench admissible?
