The section is about 8 pages with line drawings that are reproduced and credited to someone else. Copying and circulating that much would be beyond what I would feel comfortable doing. I'd suggest you either purchase the book, or request it from a library. You can also contact the APRL at:
http://stamps.org/Library-Services to see if sending you those copies would fall within the copyright rules. Sorry. Maybe someone else feels differently.
