Can anyone identify this shower cartridge?

[ReillocSW]

I cannot for the life of me find a replacement for this cartridge. I think it's a Glacier Bay but there are no markings or part numbers on any of the cartridge or faucet parts.

IMGUR link with more photos here.

Any help would be most appreciated.

Looks to be a valley or a delta
