[GreenKeys] KS-5928 L7 loop supply?

[John W9DDD]

That stack probably is germanium diodes based on vintage.  I have stack that looks like that, but I think slightly smaller.  I also have a WU 9100 wiring cabinet with one of those in it.  Does this say GE on it?

Anyone know what it is supposed to plug into? Also, I think this has a selenium stack. Leave as is? See pix (cover removed for the photo).
