John 'Vivian' Prestwich, the son of John Alfred Prestwich (founder of JAP motors), is here astride a 250cc Diamond powered by his family product, a side-valve JAP engine. The photograph was taken at Brooklands on Nov 23, 1920, and his little machine made 62.39mph, an impressive figure for a baby sidevalve engine, and a new 250cc record.
|From the books, 'The JAP Story; 1895-1951', published in-house a year before the founder's death in 1952. I'm still looking for details of Vivian's later life (and death - WW2?) - if you have any leads, they're welcome...|

Safety gear for racing had yet to become standardized or even universally worn; it took a few well-publicized, horrific racing accidents to emphasize the need for leather, and helmets, and boots, and gloves(!), all of which would become mandatory for racing in just a few years. For the top photo, though, there's a lovely purity of a man 'at the edge', a highly romantic moment in history.
