I have a book entitled DINERS, by Karen Offitzer. I bought it as a gift for my father, who used to manage the very type of diners you are talking about. I feel pretty sure the book has a picture (page 64) of one of his diners in there. As a child, I spent countless hours in them to the point of boredom. I saw one of his diners being built in New Jersey, later to be transported and slid into place in West Chester, PA. When my father passed away, the book came back to me.
If you have any interest in it, send me a personal message or whatever the board allows.
