A.I.D. Inspectors

[Rich Payne]

I 've come across a reference in a general history of Norton motorcycles to the fact that, during the war years, "...two Inspectors from the A.I.D. were based at the factory with the authority to visit any department and inspect the work..."

In my ignorance, I confess that I don't know what "A.I.D." stands for and none of my reference books have helped, neither has searching the forum but it is such a common word.

Could some kind soul enlighten me as I'd like to look into the National Archive records and can find nothing (relevent) on-line.

Rich.
