The sticker wont tell us much more than what we already see in the picture. My guess would be it is a CS201*(where the Asterisk could be any letter, i believe denoting the year or model era).
The real question is what exactly do you want to do with the mower, freshen it up to use as a daily driver, or a full resto to keep as a mantle piece. To what extent do you want to restore it; ground up nut and bolt restoration, or a repaint, a thourough clean and a once over to make sure everything is functional.
Depending on what you want to do, and whats damaged and needs replacing will determine where you start and end. We can also determine the year of your mower as it's cast into the engine block directly underneath the carby, although the carby will have to come off in order to see it.
As for decals im not aware if they're available but a call to a reputable Victa dealer, or preferably a Victa gold dealer, will determine their availability.
