Is there a book or even a magazine article with a good structural description/cutaway drawings of the P-66? Both books and the net references I have seen are very vague. It seems that 99 % of Internet articles are based on basically the same few books (American Fighter/Bowers & Angelucci; General Dynamics/John Wegg (Putnam) and Jonathan Thompson's Vultee book), none of which has much detail.
