Ryan ST-M Repair Manual

I'm building a Ryan STM replica from a set of Ev Cassgeneris drawings and I wondered if anybody knows of a assembly or repair manual avaelable. The military must have had one published to be able to work on these trainers. I suppose I could go to the Smithsonian I just haven't gone that far yet. Anybody?
