Fitz & Floyd Cups with Saucers

Fitz&Floyd's set of espresso cups and saucers don't help with my grey and gold obsession.  I love them. Oh so much.  Does anyone know if there is a matching china pattern anywhere?  This set is listed as 'vintage' on Etsy, so maybe the pattern is long gone.  Sigh... until then I will stare at these little beauties...
