VW notes...

I was in a bookstore in Berkeley a few weeks ago and found an older copy of John Muir's, How to Keep Your Volkswagen Alive. While I was thumbing through, these pages fell out and landed in my pocket. Not normally a thief, I thought that it would make interesting reading - some random VW's notes. So here they are. What seems odd is the lack of timeline in the notes. I'm thinking they were transcribed from a larger pile of receipts?
