Premier Bayview Trying to ID this shower cartridge

[DanBaltimore]

My shower cartridge is leaking so I removed the cover but got stuck trying to get the large retaining nut off (don't have a big enough socket). Was wondering if anyone might happen to recognize this brand?

From the appearance it looks to be Premier Bayview. It was also marketed by many others. You need 133504 and 133505.

I'm having a hard time getting the nut holding the cartridge off, the nut is pretty much flush with the face of the shower wall so I can't get a wrench on it and I can't get a socket head on it because it only has 2 flats. Any recommendations? Why they didn't make this a hex head I'll never know.

with two flats you use a Crescent wrench to remove it.

Thanks for the help. Finally got the valve off with a 1-11/16 crowfoot. Cartridge is labeled HJ-40!
