And just to muddy the waters a bit further, they were also supplied to the RAAF.
Our president at the time bought one from a Defence Auction resplendent in Airforce blue with a rondel on the air box lid.
Unfortunately it was stolen from his home at Fairfield.
AFAIK it was the only RAAF WDB0.
We did publish a stolen bike report so if I get some time I will go back through the Banters to see if there is an engine & frame numbers to see if it is in the register.
Not sure if it was part of the original order, or a separate bike acquired for an RAAF evaluation as in those days each branch of the services ordered equipment individually.
