I am scanning some of my American instrument manuals and will post here.
The first few are scanned from RAAF publication 413 and were printed on narrower paper than the US documents so were scaled down to fit. I have pdf'd them the size they are in RAAF 413.
These are all compass documents but I hope others will expand the thread.
First up will be these documents. 05-15-3 is missing and 05-15-5 is missing pages.

05-15-2 Magnetic compasses B-12, B-16, B-17 (43-05-25 r43-09-05) OCR ww2.pdf
An updated version of 05-15-5 that is renumbered to 5N1-2-8-1 -- from a photocopy.
Note only a few pages have the new TO number on them.
For aircraft and engine manuals the new numbering system is far better. For everything else the old system was easy to decode with only two variables and a sequential final number, the new system - no way.
