Can anyone identify this Shower Cartridge?

There is no name on the shower faucet. I uploaded two photos.

Thanks!

Might be gerber 7007 (if the stem has flats)
Looks like it has some type of adapter attached to the stem.

I think it is the same as B&K BNK7005 ; same as Harden Brass HAR7003 ; Kissler - 46-5154; Belanger FC9AC008; etc.

BK888-538

It looks the exact same except for the stem where it connects to the faucet handles. Mine is slim and flat, the one in Home Depot link has groves. Can I swap that brass stem piece?
