I think thats the base for a V121 from 1972-1973, basic series 70 MKII engine, zip start with a G3.
The Model name at the Victa ends was the Mayfair, but it was often called contessa, depending on what the store (in this case retravision) chose.
I believe Victa generally limited the name choices to a few different options, but enough options to make sure you could have a different mane to the guy next to you.
