A good reference source?

[Rock]

I wonder whether anyone can suggest a good reference source that would provide me with some discussion of the Cellini range -vintage & current. I don't mind if there is only a chapter on the Cellini in a more comprehensive text, but I would like to access some specific information as that obtained from the net has been very brief and superficial.
Alternately, if there IS something on the net that I have missed I would be grateful for the reference.
Cheers, Rocky.
