I'd like to know the specific bits and decals used on the plate on the right side of the receiver above the grip, but I'm pretty sure we know everything else that was used on this thing. I've got the Paterson piece, I've got the pen-holder, I've got the Mitchell bits, I've got an Airsoft Uzi that's close enough the rest of the mods are simple, and I have an original Uzi stock that I'm anchoring to the internals of the main gun before closing things up.
I've e-mailed around to the various Graflex replica makers and so far no one's responded to my queries about making this version -- or even just leaving off the pieces on the version used for Luke's saber so I can mod things the rest of the way. I have a 1-3/8" brass drainpipe extension tube (the actual size of the Graflex -- the 1-1/2" diameter given in a lot of tutorials doesn't match photoscaling) and some templates so that's the outer tube taken care of, but the internals are a trickier proposition, and I'd rather get a good replica than try to scratch-build it all myself. *shrug*
