Unknown Shower Handle/Cartridge

[SRHMS]

Need to identify this mfg. Cartridge is leaking, handle is stuck on. Will probably destroy the cartridge trying to disassemble so need to have the replacement cartridge in hand. Ideas? Thanks

Are you sure? If you remove the handle it's easier for us to see. That can be done without harming the cartridge.
