This is a one-of-a-kind blueprint displayed by Master Replicas at their booth at ToyFair back in 2007. It was used by MR to showcase their upcoming Luke V2 saber, although as you can see, the saber in the blueprint is actually the shared stunt. The edges of the black frame have some wear from ToyFair (somewhat visible in the photo).
