Spiral-bound training cuff checklist personally-worn and -used by Apollo 15 LMP Jim Irwin and KSC Engineer Dan Schaiewitz to develop, refine, and finalize the procedures for donning and doffing the Buddy Secondary Life Support System (BSLSS). The cuff checklist, designated as class 111 for training, includes eight thin 3.5 x 3.5 plastic printed pages (three dual-sided) attached to a 4.5″ curved metal wristband with Velcro strap, which safely secured the cuff to the astronaut EVA glove. The front and backside of the first cuff checklist page is devoted to the BSLSS donning and doffing procedure with the remaining six pages describing various EMU malfunction actions and geology station procedures. The parts number on the wristband reads, “P/N SEB 33100302-302,” with “Class III” etched into the right side. In fine condition. Apollo 15 was the second mission to carry the BSLSS, which would have allowed an astronaut to share cooling water with his partner in the event of PLSS failure. As a piece worn by Irwin during his training to become the eighth man on the moon, this is a truly remarkable artifact of the American space program. From the collection of Dan Schaiewitz, who worked as Extravehicular Crew Training Engineer at KSC.
