Anton Sipman, known as THE connoisseur of Dutch mills. But also a gifted writer and illustrator. He has visited many mills and measured them and made very detailed drawings at home. Some of the large sizes (51 cm x 71 cm!) drawings are coloured in. A specialist in mill field, with a special artistic gift. This lot contains a large part of Anton Sipman's work, published by Walburg Pers in Zutphen: Beautifully coloured, very detailed drawings in large size, 15 pieces. Razor-sharp building drawings in large size, 60 pieces. The accompanying the large drawings folder and the accompanying manual, 68 pages. Book Molenbouw, with a detailed construction description of many mill types, 551 pages hard cover with dust jacket. Book Molenwieken, with beautiful drawings of all common wheels, combs, rods and larks. Complemented by an extensive how and why, 136 pages hardcover with dust cover. Book Molens, as they were and as I have known them, with a detailed description of the operation of the catch, lining and pal at different mill types, 57 pages (29 loose sheets in the cover). Here and there may be a note. The photos give a good impression of the condition of the drawings folder and the books. This lot is a must for the very interested and motivated miller or miller in training.
