In the 1970's, Reiss Games Inc. (a subsidiary of National Paragon Corp.) offered several dexterity puzzles in their Shock Absorbers, Hand Shakers, and Nerve Wrackers series. In addition, The Romany Merchandise Corp. seems to have issued duplicates of the Shock Absorbers line, but under different names.
