This was my first bike. I learned to ride on it in Richmond Park, London. It's a 1939 500 cc Triumph Speed Twin, same age as me. I was part owner (my part being about 5% of it, I imagine!). Photo taken in May 1957 where I lived: Stadium Street, London SW10. Then a scuzzy neighbourhood, now you can't park for all the Mercedes and Volvos. Anyone else like to show some nostalgia?
