From a smoke free home, this book was well used years ago, it appears complete, there is a page that is torn out which was part of a fold out diagram that I have shown in the pictures, it could be taped back in but will come as you see it. The big problem with the book is the binding and spine are bad as you will see, otherwise it is clean for the age and would probably be able to be restored but I am not sure how to go about something like that.
