The earliest Canberra times reference to a Rotomo I could find is this, dated 12th August 1955. It also appears to be the first mention of the Victa 125cc, so probably counts as the first advertisement of the Model 1 Rotomo (non-fan, offering a pretty clear indication of the release date for this model:
