Is this Richard deKerbrech's anticipated book about Britannic and Georgic? If, so, the last I heard was on the Liners List a number of months ago, to the effect that the project had been shelved because deKerbrech's publisher felt there was no market for such a book.
It must have been another forum. I am afraid not -- but it was not very detailed from what I remember (I think it was quite thin). I seem to remember it being white or greyish and it might have been privately printed or by a small publisher. It might have been something like 'MV Georgic' -- but I really didn't take much notice. Sorry.
Here is classic photo-postcard image of the Georgic. This is taken after the second world war as she has been re-fitted with only one funnel and is also in White Star Livery. Also please note the dual house flags on the mainmast.
