Need help identifying the tub/shower faucet valve/cartridge in the pictures below. I shutoff the main and removed EVERYTHING in preparation for replacement at a later date, and realized I never took a picture of the actual CARTRIDGE itself, and want to see if I can get some experienced eyes to help identify a couple parts! (The issue we're fixing is a LEAKING tub faucet.)
I want to replace the cartridge/stem all together if possible -- but if that's too hard to identify, I took a picture of the washers in the valve as well -- hoping I can simply replace those for both hot/cold water sides. I was expecting washers/springs but this what I found when I opened up and I've never seen these before!
