Hi
Darryl, and a warm welcome to the forum. It's always nice to welcome another Scott Bonnar model 45 owner, as we all like to learn new things and tinker here.
Your machine is a 14", manufactured at the Thebarton factory in Sth Aust, sometime between 1968 and early 1976, as it has a solid deck. It is a shame that the air cooling cowl is missing; as grumpy has said, that would have given us the date of manufacture of the Briggs, which would give us the approximate date of manufacture of your machine.
Once again Darryl,
to OutdoorKing.
