delta 600

Hey! Love the forum! I need help Identifying this valve. The plumber said it was a Delta, but at the plumbers supply store, they said it wasn't (Plus they didn't have the replacement) I want to replace it because it's leaking and also get a new trim and handle. Any help? I appreciate it!

How many times does a homeowner do this to a Delta 600 when they try to remove the bonnet? If a person isn't careful, you can twist the three soft copper tubes to the body of the faucet. My fix is to cut out the old Delta 600 and install a new valve body. Moen makes an easy replacement...
