Drawing of cockpit instruments 1939/40

I have found a reference to 7 drawings of the Royal Aircraft Establishment which have the vague description of “General cockpit instruments 1939/40”.

Does anyone have a copy of any of the following drawings and can tell me what instruments are covered in the drawings?

A.66202
A.66214
A.66233
A.66274
A.66275
A.66581
A.67101
