Shower mixing valve cartridge - identification?

[PeterLewis]

Hi folks,

I have a single shower mixing valve that doesn't mix any longer. I've removed the cartridge but can't identify it. Been to 2 plumbing supply stores and no luck there either.

Going through previous posts, it looks like a Sayco or a Aquabrass cartridge to me but I'm not sure and I can't figure out the exact model number. Any help identifying would be appreciated.

Thanks to all.
