What's a good resource for identifying brands of plumbing fixtures to locate parts?

[This Wrench is Heavy]

I need to replace the cartridge in a freestanding bathtub faucet but cannot seem to locate the brand (the only identification is the word "Nexstyle" and the logo and numbers in the attached photo) much less know where to turn for parts. Is there an online or other resource for identifying the manufacturer or where to find parts available for what seems to be an "off" brand? Any help will be greatly appreciated--I don't want to drop $600 on a replacement. Thanks!

The best resource is experience.

Or you can trudge through Google images until yours pops up.

Post some better pics, wider field of view.

If you take the handle and/or trim plate off, to expose the cartridge or guts inside, or the valve body, that will usually give you the answer.
Or will let someone on here recognize it.

If that faucet is Chinese generic stuff, many faucets like that use generic parts that you can get on Amazon.

We will probably need to see inside the faucet, or see the old cartridge or stems, to narrow it down.

Is this faucet mounted to the tub, or built into a wall?
