Here you go! It's from 1943, lol.
But in all seriousness, I doubt that Disney posts that kind of current information for everyone to read. They even stopped handing out things with the character heights on them at auditions because people were posting them on the web. Disney has a big web presence and they are very stringent about what is allowed to be posted and what is not. If you have more specific questions about employment at Disney, you might find more help than simply asking for the manual, IMO.
