The second edition of Simon Moore's treatise on the 8C2900 Alfas is now available from Parkside Publications in Seattle, USA. (http://parksidepublications.com/)
It is fairly expensive, more so if you want the signed, leather covered, collector's edition, but if it is half as good as the 1st edition, it'll be a book to buy and cherish for a long, long time.
The 1st edition was published in 1986 and had a print run of only 2500. It has long since become a highly prized collectors volume with 'unread' copies commanding in excess of $AUD2000.00. If that is your thing, the 2nd edition may well go the same way.
Merry Xmas,
