There seems to be different styles of lenses on the props depending on which one you're looking at. In some pics they appear to have slightly tapered sides like a Dialco LH88 ("gumdrop" shaped), and in other pics they look more like a traditional dome with vertical sides. It's reasonable to think they maybe used similar but not exact lenses on the different props, believing viewers would not notice any difference (and TV set resolution would not show major differences). I do think taller lenses would work better if protruding from the inside through mounting holes (as they would be on a real-world device), while the shorter lenses look like they'd probably work fine if glued to the outside surface. If following the Bridge console buttons approach, it would seem these were attached to the outside.
I'm looking at the different Skivertex patterns of textured paper, and although they add an interesting surface to the prop I'm not really seeing such a texture in screenshots (unless it's just not coming through due to resolution). The way light reflects off the flat surfaces, it seems to be more like painted wood than something textured like the communicator shells. Are there clear pics of screen-used logbook props which show a particular texture? I would think a paper skin might not be as resilient as a good paint finish.
