Interesting result list , Alvin.It seems that the NSW S/C Champs were run over a number of rounds BITD and the legends that were riding in that round !!.
Another thing that struck me is that Douggy Penrose is listed as riding a CSD in the Ultra Lightweight and Lightweight, now that's gotta be Clement Sorrel Daniels bikes, the tuning whizz from down the 'Gong way, have you got any clues on that , Pete ??. 'cos I thought Clem was a road race tuner.
