Fine scale aircraft building is absorbing. However sometimes it is a real thrill to get to see the actual manuals, plans and blueprints that were used to build these aircraft back in the 1930s and 40s. I guess collecting and browsing through these types of documents is a major hobby for me. To date the most reliable high quality and unique original source material that I have been able to locate is on the following site which is run by real enthusiasts. I have attached the link below. They have a certain amount of free stuff and also auction a lot as well on eBay.
Thanks for the link. [Y] Looks like a great one.
