Perhaps it's this one from Rohl and Perrin and Rowe?

Thanks Plumbed Elegance. Unfortunately, we do not have the exact spec for this faucet as our archive files are corrupt and can not be opened. I can tell you we are very fond of Rohl and Grohe. I recommend contacting your local rep for matching assistance.
