Next up a partial AP 1095A Aircraft Indicators.

This is a scan from a single sided photocopy that was, from the multiple edge and binding hole shadows, a copy of a copy of the original. It was impossible to work out the original page sizes and the foldouts had been reduced in size to fit the paper at some stage.

It is missing most of the introduction section (Title page, Amendment record, etc) and several sections and pages are missing.

Whereas the US had a single wiring system for all aircraft the British had many different systems, five of which are listed in section 3.

Below is a listing of the contents of the PDF

MMM interesting - I downloaded and viewed the files at the Bundy library between medical appointments and they opened with no issues. I downloaded them when I got home and never checked them and all three are showing as dead files. I guess he read my reply and deleted the files while I was downloading them.



I will PM him and ask him to repost them or to email them to me using Wetransfer.
 
Here are the first batch from pb43. All nice clean copies with their covers.

Section 24 refused to upload in that post so I OCR'd it to see if that helps. OCRing often drops file size as a side benefit. I do not know if size was an issue (I doubt it but you know computers).
