And even before that when Williams General Aviation operated a fleet of PA31s daily ex AD. Some callsigns that I can remember are WGG, WGK, WGI and the unfortunate CIZ. They were followed by the mighty C500 WGJ.
And of course before all of that in about 1970 or earlier, one of the first PA31s in Australia VHDAP flown by Tony K, now a principal of Airlines of South Australia. The company was Aviation Services at PF. I believe that contract was for DELHI (Australia) Petroleum hence DAP.
Time for my warm milk now and toddle off to bed!
