Minitron / Pinlite
I found a few cool misprinted minitron style 7 segment incandescent displays. Essentially, they are numitrons that are in a flat pack. As best I can tell, they were primarily used in the aviation industry because of their dependability and durability. I'll take some more photos of them in use after I figure out their pin out. Stay tuned.
