Jeff, you probably already own the booklet put out by Magic, Inc. in 1970, but just in case:
Dai Vernon's Expanded Lecture Notes
Begins with Cups and Balls then covers
The Changing Cards
Name a Number
Thought Card from Pocket
Hints on the Side Steal
The Migratory Cards
Bluff Card to Pocket
The G.W. Hunter False Shuffle
Two Cards to Pocket
Two Cards Through a Magazine
Expansion of Texture
Ball, Cone and Handkerchief
A Chinese Classic
The Thumb Tie
Coins and Cylinder
The Forgotten Trick
Follow the Leader
The Snap Crimp
A Mental Discovery
As you can see, all of the tricks that you listed above are contained in the booklet, along with others. I would surmise that your set of notes was from an earlier lecture and that the other effects were added to create this "expanded" offering.
Dates of lectures cited in the text are:
S.A.M lecture in Chicago 1954, December 1, 1946, S.A.M. convention in Philadelphia 1968 and Chicago,July,1965.
There is a note in the text that from The Thumb Tie on, is taken from a lecture in Chicago, 1954.
The way the booklet is put together seems to me to reinforce that it was compiled by taking an original set of notes and fleshing it out with effects that were from previous or later lectures. There are some wonderfully-done illustrations for Ball, Cone and Handkerchief, A Chinese Classic and Gemini Cards which were probably on the three pages of illustrations in your set of notes.
Reading the comments by Jay Marshall and others in the back section is very illuminating.
Hope this helps!
It's never crowded on the extra mile.....
