Metal Halide ballast info

[Bartman]

Hi All,

I just bought a used MH/NO fixture and I have a few questions. I'd like to buy new MH bulbs and it looks like the ballast is a probe start but I can't tell. Can anyone identify this unit? The previous owner thought this may be a Hamilton fixture but if anyone recognizes it that would be great. The unit seems to work fine.

Also, can anyone suggest a good place to get a better reflector for it?
