┆Blueprints for the 21hp, 30hp, 40hp and other Lanchester models, including the Lanchester Armoured Car. Three index volumes of the blueprints are also included. Each complete blueprint (and the index volumes) were digitised as part of the Lanchester Interactive Archive project, as were individual drawings on each blueprint.
The online catalogue only shows a sample example of the blueprints at the moment, but more information will be added as soon as possible.
Each complete blueprint (item level description) and the index volumes are shown, plus the individual section drawings of parts (piece level description) on the blueprints 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 (or sectional drawing numbers if there are several drawings on a blueprint) are given as alternative reference numbers (to distinguish from the archive reference number).
Positive images of blueprint negatives (previously sorted in a separate series) are also included where available.
Notes on cancelled and updated drawings are included.
