Pretending/Simulating Right Below Elbow, Body-Powered Prosthetic Arm, Hosmer Model 5 Hook, Figure-8 Harness I have personally used this arm countless times so I can confirm it is in working order. If you would like to simulate/pretend being a right below elbow amputee, this arm will do just that. It doesn’t look like the vastly more expensive pretending arms but it simulates the functioning of a body-powered hook. The Hosmer Model 5 hook can be easily swapped with another terminal device by unscrewing the nut on the back of the threaded bolt.
