G'day , Michael
Great to see you on here, I remember Doug very well , he was a very exciting rider to watch and to chase !!!, there is a pic, not a real good one, from Revs of Doug, Kevin Patton and myself at Yass with Gough Whitlam on Doug's bike on page 3 post 39 on this thread.
Slides will probably have more info than me , however he's at the Nepean 2 day Charity Dirt Track right now.
