looks a lot like a /950.
it looks pale greenish in sunlight when off.
print very faint or i would post a pic.
i got 2 of these many years back when my shop was hired to remove a very large (...) scanner.
this thing had all sorts of interesting parts in it.one of which was a working but rather large argon laser that brought a bunch on ebay.regret stripping it but it had to come apart to move it even a few blocks to my shop.i still have the fixture these lamps came from too.think 2 tube desklamp head .
not sure if it was for the operator to match things or the unit used it as the light source for imaging.
the censor thinks h e l l is a cuss.
its the brand of this unit.
