Two books of mill sketches, some of the same mills as in MUNN-02-01. . Every double page spread is numbered and the numbering continues from book 1 to book 2. Each right hand page has a mill sketch, with the facing page often containing notes on the history of the mill. Each double page spread has been given a separate catalogue entry using the original numbering (e.g. sketch 1 has the reference code MUNN-02-02-001); where the facing page is blank this has not been scanned. Sketches 1 to 74 are in the first volume and 75 to 143 in the second volume. Loose sheets stored with the volumes list the sketches and continue to list a book 3 (sketches 144-185), no longer extant.
