I can't speak for Jack but if I recall, volume 2 of his Gas Pump book says values shown are for a pump that is in about 100% original unrestored condition. Volume one also said there were five other people besides Jack that got together to come up with the values based on their knowledge and experience in the hobby. The five that helped were names in the hobby, their input should carry a lot of weight with others. That said, the books are several years old already and prices/ values do change. They should be used as a guide. Volume three should be the best yet.
