Analysis of the Airflow Around an MGA Roadster (pdf)
Posted on: Thu October 21, 2021
This study was performed in 1963 by J.J. Cornish III of the Mississippi State University (MSU). The intent was to identify the aerodynamic issues which are present due to vehicular contours and design. The MGA was chosen as it was "a typical open sports roadster".

MGB Schedule of Repair Times (1962) (pdf)
Issued in June, 1962 as the MGB came to North America was the "Schedule of Repair times" for dealership warranty work. This "confidential for trade guidance only" document makes interesting reading as it gives one a good idea how long the factory believed certain service and repair procedures should take a dealership technician. Some of the times given seem generous and some rather skimpy.
