┆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 in 2016, as were the 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.
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 are also included where available.
