A repurposed Army field message book labelled, "Norfolk 1927" containing notes taken from a four-day tour of over 30 Norfolk windmills. The notes contained within the bound section of the notebook are brief (only 26 pages in all, the remainder of the bound notebook being blank). However, a self-addressed envelope at the rear of the notebook contains 19 pages of Wailes' narrative account of each day of the tour, written up from his lodgings each night and including notes of his encounters with two millwrights, Robert Martin and Dan England, as well as various millers and mill owners. Also at the rear of the notebook are three single sheets of notes including an account of the raising of the windshaft at Billingford Common Mill, near Diss. Identifiable mills visited which feature in Wailes' narrative are listed in "Place access points" below.
