Hi, I'm looking for a new companion fixture for my GE MVS-175 175W MV security light from 1987. 

Ideally I'd like to find the 70W HPS variant (DHPS-70), or at least the 100 MV version (DMVS-100) that I could convert to HPS. Condition doesn't really matter, even if missing refractor. As long as it's presentable.
If I can't locate one of these, another GE 201-SA HPS NEMA (preferably 1st or 2nd generation) is something I could use as a alternative. I already have a refractor I could use so just the head is acceptable.

Open to purchase, or trade (I'm considering the GE OWL 50W HPS unit).   



Thanks.
