I use everything I can get my hands or eyes on:

Squadron Signal books

Aviation in scale books

Bentley Drawings

Zeno’s warbird drive-in videos

Designer Plans: Bates, Ziroli, Platt, Smith, Vailley, Etc.

I’m always looking for a photo of something, so if you have some…scan them and send them to me…helping me, will help us in the future. I need gauge photos at present (straight-on if possible ).

I will post some links to helpful sites as I get time.
