Here is my 42WLA when I got it, in about 1972, still in Royal Australian Air Force MP colors.
And a year later, on my 16th birthday, on my way to take my drivers license test 1n 1973. Cops freaked about the hand change and basically wrote out my license while I rode up the street, turned around and came back.
Here we are more recently.
And here is my "other Flattie" the Norley Flatinator - servicar engine in a Norton Dominator Featherbed frame.
