If you've got any meters kicking around and might be willing to bring to the show, I might be interested! I am especially interested in finding a "solid face" GE I-60-S meter (example shown is a GE I-55-S), and am also still looking for an early GE I-20-S (S/N needs to be in high 16 million range - example shown is an I-16 socket conversion). Also interested in any very early electronic / mechanical hybrid meters (the example in the middle is a Duncan MS-II with ripple control).
