Two reports by Nicholl's co-director, Chris Wallis, on Bocking Windmill, Braintree marked "DON Purely for General Background Information". (1) Six page manuscript report (pages 1 to 9). Details the condition of the mill with a recommendation that preliminary work is carried out to expose hidden timbers allowing their condition to be assessed, a complete dimensions survey to be taken and a priced bill of quantities to be drawn up. The cost of this preliminary work (including the removal of the sails and stock) is £600. (2) Four pages of drawings and measurements (pages 10 to 14) for works to improve the mill's stability. Includes drawings for a steel beam support to the mill's broken shears as well as for a cranked beam.
