I found it behind my workbench today. 1979 original, printed in Italy. Pages all intact and in good condition. There are 2 pages with some writing, only a few words in biro on each. Offers please. I can send pictures. Thanks.
Its demand that determines prices on such items as ell as the pestige of the model. I bought a really nice original Le Mans manual for £15 with free postage. Those are quite rare so i guess maybe not as high a value as you might put on it.
