Computer History Museum, Silicon Valley. The Museum holds and displays a number of LEO II relics including part of LEO II/3 the Corby Stewarts & Lloyds machine, and various LEO books and documents. Its record of holdings with photos is well organised and include the oral history of LEO veteran Chris Date.

LEO has an entry on the museum's website.

The museum's senior curator, Dag Spicer, is a member of the LEO Computers Society and its American correspondent. 

The Museum also holds a marketing film made for LEO and donated to the museum by John Pinkerton

More information about the LEO II/3 at Corby including 2 newspaper articles can be found in the museum's website. The catalogue lists these articles as 'The Review News: A Newspaper for the Employees of Stewarts and Lloyds Limited, no. 67, July 1957: front page article titled "Electronic Computer for Corby, 'LEO II' will make its bow within the year"; and Steel News: The Newspaper of the British Steel Corporation, no. 50, 15 July 1971: front page has article titled " After 13 years LEO is out of commission".

On 18 February 2021, Dag Spicer, senior curator of the Computer Museum and American correspondent of the LEO Computers Society, presented the history of the museum,  in particular its affection and holdings of material related to LEO.  Dag defined the Lyons/LEO story as a promontory in the evolution of computer use – a very apt definition.  

The presentation was via Zoom and finished with a question-and-answer session. A recording of Dag Spicer's presentation can be viewed on the LEO Computers Society website.
