My husband has had a number of these sort of books for a number of years. He was forced tried to get rid of them to the local old book shop, only to find that they weren't old enough! He then said he knew someone at work who would have them, it has taken him a very long time to get around to taking them in to work. They are going tomorrow and after a very busy day and no blip they were the obvious get out clause choice.
