From Phil Dickson, grandson of Vince Sim:
I’ve stumbled across your wonderful site because I’m researching the family tree, and hence trying to get more background on what my grandfather actually did for a crust. The family all knows he worked at OTC but no one can put their finger on exactly what he did.
My grandfather, or Pop as he was so well known, was Vince Sim, who sadly passed away in 2002 at 92 years of age. I have great memories of the staff houses at Doonside, the tennis court, the parties, fooling around down at the creek etc which is why it’s been good to stumble on this site full of great photos and anecdotes.
So if any of your visitors could shed some technical light on what Vince actually did at OTC (I know he was at Pennant Hills and moved out to Doonside) it would be greatly appreciated.
