all excellent points mentioned above.
the bowyers bibles, Torges's book and Comstocks book are all excellent reading material, and i recommend reading them all.
although , i have recently acquired this book, and IMO its the most clearly written, well researched and well illustrated book ( in fact it actually has more colour pics than there are pages in the book!!!
) on the subject i have come across.
i would highly recommend reading it.
I believe the author worked with Comstock on it.
