Being an old guy around here and in the prop hobby most of my life, I've seen phasers and communicators and a bunch of other original stuff.
But only one tricorder. Saw one at the Smithsonian Exhibit and the same one at World Con.
Herocomm.com does a great job with the comms, and MR duplicated the phaser from Greg J.
How many tricorders were made?
How many still exist?
I am sure who has them is a guarded secret but, does anyone know any of this other info?
