The Pouzin article would have to be about the 
earliest reference, since the first version was 
produced in March of 78.

Anyone with an SC16 archive should have them.  I 
believe I have the first 300 or so documents on 
Microfiche somewhere.  You are looking for 
SC16/N46, N117 and N227.  These were the outputs 
of the Washington, 78 meeting; Paris, Oct 78; and 
London, 79; respectively.  The DP version should 
also be around which would be Berlin 1980.  The 
document went through a complete re-organization 
between 117 and 227.  The Babbage Institute has 
the proto-version of that document.

This is the London output document.

Layering did not originate with the OSI model. 
The model really just wrote down what people were 
thinking at the time.  There had been talk of 
these layers all through the 70s.

Further questions on the OSI stuff let me know.
