I hope you don't mind me taking the liberty to add two pictures (scans) of this drawing's original (of which I am the happy owner). More than a photocopy they show the true value and information of the factory drawings. There is considerably more tone on the original's scan. The detail far below (400 dpi true size) shows the fabric, corrections and related details of the design drawing process:

This is the factory drawing for the base of the Austin Westminster Countryman, this model was not produced. As can be seen the sales number would have been 155, this was allocated to the Ford Anglia 105E in 1961.
This image has been graciously donated to the DTCA by Mike Richardson.

This is the factory drawing for the unissued Renault Fregate, drawing dated 4th July 1957.
These image have been donated to the DTCA by Mike Richardson.
The first image is from an A3 Scan from the publisher of the Richardsons' books, the second is a photograph of a factory photostat.

This is the factory drawing for the Aerial Assembly for the 969TV Extending Mast Vehicle, produced from 1959 to 1964.
This image has been donated to the DTCA by Mike Richardson.

This is the factory drawing for the base of the 173 Nash Rambler produced from 1958 to 1962. There was also a 257 Canadian Fire Chief version from 1960 to 1969 (hence deletion of the sales number).
