Which cover plate for shower faucet?

I need to find a cover plate for my daughter's faucet valve in her shower. I removed the handle and took a picture hoping someone could identify who the manufacturer is. You pull the handle out to adjust the water flow. There are some Delta faucets throughout the house, but not sure which this is. I put that tape there so she could use it until I can locate the proper plate. Any help would be appreciated. Thanks!
