Hi James , the cd you refer to is basically a compilation of all the BSA parts books . there are actually two CD,s . one has the books from 1914 to 1930 and the other from 1930 to 1939 . they are an excellent referance to have.
I seem to have lost my information on how to contact David Brailey but I beleive you can get a copy of these from Jon Paul Bingham , contact him
