sweitzel: I don't think the gun itself is crooked, just the base.
ctc17: OMG, those bastards DESTROYED that tube!
You're right the mask looks quite sturdy, though as you have seen it's possible for UPS to ruin ANYTHING. Don't those people have standards? I mean, how is their business model viable if all they do it break stuff all the time? To answer your question, no it did not have safety glass because all rebuilds have to have the panel off in order to go through the oven. My set has a flat pane of glass anyway, I wouldn't put a bonded tube in there if I could possibly help it.
freakaftr8: I think what you are seeing is just the edge of the last color bar, I don't remember if there's another one. It's definitely not a shadow.
To all who asked: I'll take a pic with a blank raster for you. I'll cycle through each gun too, so you can see what I mean about how the pattern changes.
