Briggs Mfg. Barry Walter Co, Need help identifying bath stem

[RTD21]

Hi!

Does anyone know who makes this stem?

Also, how does it come off? I removed the threaded nut in the first picture and it doesn't budge.

Thanks!

With your trim the faucet was sold under Briggs Mfg. Barry Walter Co. still makes a replacment cartridge. # LF467031
You can see it on page 461 on the link. Many plumbing supply companies purchase from them or you can call them for a local distributor. To answer your question about removing it, The nut you removed is the only thing holding it in. Put the handle back on for leverage and pull with a left-right motion.
