A DS1 in Australia

I live on the East coast of OZ 100 miles south of Brisbane. I have recently purchased a DS1, although it was sold to me as a DS2. No probe, it's in good condition and ready to sail. However I am confused about several of its characteristics. Perhaps someone can explain. Firstly it has moulded seats with bungs, a motor well on the aft deck and gunnel rubber strips that terminate at the end of the side deck, not halfway across the transom. A DS2 I thought.
But then it has a visible CB pin that has been glassed over it no lever. The CB is a slab of metal, definitely not hollow but it is raised by a line that comes up through the aft end of the CB case and goes forward to a pair of triple pulleys attached to the top of the mast post. No haul down for the CB, just up and its heavy.
It has blue decks and white hull and no timber other than the removable floors. No ID plates anywhere and the sails are not from a DS as they have a strange Q16 insignia.
Does anyone know what I have? I've read every post about model ID's and looked at the spreadsheet but I can't make any sense of it.
Thanks, Greg
