Looking for original 1920 printing of 'A Treatise on Airscrews' by Whyrill E Park. Must include foldout drawing between pages 162 and 163 and another foldout drawing between pages 172 and 173. Cover quality not important. Pages must be clean and free from writing. Not interested in current reprints available on ebay and Amazon.
Thanks CL
