[GreenKeys] Mystery rectifier

[W9DDD]

Anyone recognize this?  Kind of WU flavor?

Probably goes to land fill unless someone has a need.  Was bolted in the 
bottom of 28KSR cabinet but wasn't "active".  No other indications of WU 
on this RO.

One of the other KSRs has a WU ESU, any pointers for a WD on it? 
Haven't dug into this one far enough to look for name plates.
