This document was generated by me, Colin Hinson, from a Crown copyright document held at R.A.F. Henlow Signals Museum. It is presented here (for free) under the Open Government Licence (O.G.L.) and this version of the document is my copyright (along with the Crown Copyright) in much the same way as a photograph would be.

The document should have been downloaded from my website https://blunham.com/Radar, if you downloaded it from elsewhere, please let me know (particularly if you were charged for it). You can contact me via my Genuki email page: https://www.genuki.org.uk/big/eng/YKS/various?recipient=colin

You may not copy the file for onward transmission of the data nor attempt to make monetary gain by the use of these files. If you want someone else to have a copy of the file, point them at the website. It should be noted that most of the pages are identifiable as having been processed my me.

______

I put a lot of time into producing these files which is why you are met with the above when you open the file.

In order to generate this file, I need to:

1. Scan the pages (Epson 15000 A3 scanner) 2. Split the photographs out from the text only pages 3. Run my own software to split double pages and remove any edge marks such as punch holes 4. Run my own software to clean up the pages 5. Run my own software to set the pages to a given size and align the text correctly. 6. Run Omnipage (Ulitimate) on all the pages to OCR them. 7. Generate a searchable Acrobat pdf file.

Hopefully after all that, I end up with a presentable file, though I can’t guarantee there aren’t errors in the OCR. If you find missing pages, pages in the wrong order, anything else wrong with the file or simply want to make a comment, please drop me a line (see above).

It is my hope that you find the file of use to you personally – I know that I would have liked to have found some of these files years ago – they would have saved me a lot of time !
