This is a 8-page Press Information letter issued by The Nuffield Organization on or about June 1, 1958, with a note to not release the information until July 15, 1958, the official release date for the MGA Twin Cam. Click for larger 1.3-MB pdf copy.

This letter is likely to have been sent out along with the letter inviting press people to the Twin Cam Demonstration Day on July 14, 1958 (one day before the official release of the MGA Twin Cam). This letter may also have been available to press participants on Demo Day, but was probably not inside the Press Information packet.
