Series

┆Each complete blueprint (item level description) and the index volumes pages are shown, plus the individual section drawings of parts on the blueprints (piece level description) to provide larger images. This includes some section drawings that were cut from complete blueprints that are not in the collection.  The original blueprint numbers and section drawing numbers of parts are given as alternative reference numbers (to distinguish from the final archive reference number). Copies of the images that have been enhanced post-digitisation have also been included to make then easier to read - these have an E at the end of the archive reference number. Positive images from blueprint negatives are included in this series where available - these are indicated by an N at the end of the archive reference number.  Notes on cancelled and updated drawings (e.g. a later date than other drawings on the same blueprint) are included where available. Some images are of poor quality because of the condition of the original drawing (e.g. through handling & use, light damage), especially if the images have been enlarged for different section drawings on the same blueprint.
