I am very grateful to Andy Read for all the help he has given me and the wealth of information he has supplied, and also to anyone else who has, consciously or unconsciously, helped me compile this gen. People like Gary Thornton, Denzil Morgan, Neil Aitken, Mike Kennard and others too numerous to mention. Gents, you know who you are and I'm grateful, and if there's anyone else out there who feels they deserve a mention e-mail me and I'll add your name to the list.
