Here's a pic of a Super RARE Victor Master Hand Gripper (right, w/3 springs) from the 1920's! I recently purchased this hand gripper from Dennis Rogers from a collection he had bought. NOTE: I have searched for over 20 years for one of these hand grippers! The ad behind the gripper is from a 1926 Strength magazine. Take a good look because you may possibly never see another one! ENJOY!!!
