When it comes to serial numbers, others here will have to chime in as I don't know. 82 seems late for this machine but it's maybe possible Victa stretched out this design that far for export at least Some were sold in 1980 here.
I have never seen that height adjuster handle and teeth fitted to this base. Another export feature?
I have a feeling this got a different set of labels to what Australia got, but whatever it was, it's not likely to be reproduced, so may as well run with one of your choosing. It will set it off well.
