Wanted: Aqualine/AB UV glass shield

[Winters]

Hi everyone!
Would anyone here have an AB/AquaMedic/Aqualine UV glass shield for their MH light pendants, such as my Ocean Light 250? I can't remember the actual dimensions now but they are about 4"x7"x1/8" or so. I've looked at Halogen lights' shields and none are the right size. I've gotten an order going from the manufacturer but I was hoping to either buy or borrow another glass shield in the mean time.

Any help would be quite appreciated.
