Gidday Jim- there's a Rochedale near Brissy too... if you're not a drinker you soon may be !
Maybe it left the factory as a Road Rocket, but with an A7 Engine, you'd have to call it something else..may be a 'Road Star' or 'Shot Rocket' or something.
... unless at some stage the cases needed replacing, then it's just a wrong number?
You need to know all this stuff before you start, even before enlisting help.
Maybe paste a piccie or two and you could have an endless list of suggestions.
You should be able to at least tell if it has (some) A10 internals by measuring the stroke with about a 6" piece of wire down the lug hole and measure the difference between top and bottom dead centres, and count the fins on the barrel- should be 8
They're a fairly simple and reasonably straight forward machine- I new Jack-S about 'em when I bought my first one in bits in '75 and still learning- you'll soon be an expert
Find yourself some literature, maybe before you pull it apart- unlike me...good luck, there's plenty of help here
