Delta shower. Help identifying this shower's cartridge

[GaryArm]

Another plumber replaced the cartridge for this shower and used the wrong part. For one thing the valve should rotate to the right so that it's horizontal. For another the mixing doesn't work correctly. Can anyone help identify the correct Delta Monitor valve?

If you pull the handle this chart may help.

The "wrong" cartridge would not fit into the body, and the body notches and stem "stop" determine where the handle is when the valve is off. It cannot be changed.
