G'day Pete, I saw that bike and was nearly going to have a go at it myself. It looks like a nice bike. The colour was used on the Star Twins of the era.
Dont worry about the numbers, just get it up and going and ride it.
Getting more of us Aussies on the forum, we'll overtake the poms at this rate. I'm in Mt Gambier in S.Aust (crow eater)
