Hi Thursty and welcome
You have come to the right place a wealth of knowledge here with the likes of very experienced people in this field as well as many others doing a diy restoration like myself.
You will find that the engine is a 3hp 1986 Briggs and Stratton and the machine looks to be a later 17" model 45 Scott Bonnar which I'm I'm pretty sure would of been made by Rover in Brisbane going by the engine date but I'm sure someone will come along and give you more info regarding the machine and engine history.
We all look forward to your progress as you will no doubt become addicted once you get stuck into it.
Cheers
Bon_Scott
