One observation on the communicator I want to mention is that the faceplate layer below the one that is lifting is bare brass sheet/plate. The rest of the gold color pieces are a slightly different color... it is supposedly made of machined metal - maybe the other gold is gold anodized aluminum? @RustyH were you able to make any observations about that?
A question for the board... what kind of screws do you see on the lid hinge? Grub/set screws or tiny socket head cap screws? The comm in Vegas had one of the screws on the right partially undone but I didn't notice until reviewing pics later, so didn't think to look closely in person... It seems like the inner disc might be separate as the one on the side with the loose hinge seems a bit crooked, which points more to a cap screw than grub screw.
