The photo was taken with a cell phone camera, so it's not the best. https://i1208.photobucket.com/albums/cc361/loumaffei/ksu.jpg

Is the cover for it still around? Beige was usually ITT or Stromberg. Gray was usually WE. I don't remember the others. There were several. Those 1A2 parts were so universal. - Dave S. - You can never appease your ideologue opponents.

Most of the stuff here is/was WE, but in the early 1980's there was some ITT equipment installed. The cover is long gone, but as I recall they power supply doesn't have any manufacturer markings on it either. As you can see from this photo they pretty much use the "abandon in place" method for any of the old or decommissioned telecom equipment. There are very few people left here who know what this stuff is, so they just leave it alone.

If you look at the WE gear it was as close to bulletproof as you can get. The other stuff (like this ITT unit) was good quality, but not nearly as indestructible. Maybe it didn't have to be. Fast forward to today and look at all the junk that we import from China. It doesn't even come close. I sound like an old man, don't I? Lou
