G'day wce and all Many thanks for that important image. This does add to the history record for the Victa Concorde.
There is no store branding. - but I do not believe it was part of the factory Victa range of the time. That it is listed in the Victa Code system in the late 1980s is telling. That requires a separate explanation.
My best guess is that this is a Victa 'Stencil' offered to various mass-merchandisers, but with an additional trick ...
The store was not identified, but the model name was unique to the store. Hence, Celectial to Waltons, Concorde to Betta Electrical, Pace to Norman Ross, etc.
Of course, this arrangement was only offered to the 'big' accounts, and I guess, for a limited number of years.
We have certainly learnt more about the Victa Concorde thanks to your posts. Thanks to Mowerfreak for the accurate dating.
