Firstly: I’m very relieved to hear someone mention New Eye Studios. I thought I was the only one who remembered them.
As for the Tricorder shine: I’ve wondered this myself. The originals I’ve seen in real life or pics are never shiny…but they are always pretty beat up and grungy, too. It seems to me like it would be very hard to tell even if they were once shiny.
Here are a few pics I took of Paul Allen’s Tric at MoPop, though I realize it’s not “Wah A or B”. Very beat, shiny on the corners if the light hits it, but not overall.
