The controller stamps are NOT to be used in most dating efforts, in fact, some controllers had secret identities.

The inspectors mark is still an secret so the list here should be regarded as uncertain, but it can in some cases give a more accurate dating that the stamps.

What is the date code above the controller stamp?
If there is none, it puts it before 1922.
