Hello Bushwacker
I know it is 5 years since you put that question in about Ken but it has only been brought to my notice
Ken was my brother and was killed in 1973 on his bike.
He did indeed race at the Mallory Park Race of the Year in 1969 on his Norton but finished second to Agostini as he had done at Cadwell Park the previous weekend. These results were fairy tale as he beat all the top riders of the day including Mike Hailwood and the following season got sponsorship from Paul Dunstall.
Just to clarify a few things Kens' bike was indeed his converted road bike which he had been racing all year as a race bike. but he took the bike down to Mallory with his mechanic Kieth in his Transit van. It would have been fantastic if it had happened as you remember it but alas no.
As a matter of interest there is going to a large article on Ken in the June issue of Classic Racer.
