It looks like it is apx 1970 to 1973 model. (I have a 1967 model similar)
This company in Rushcutters bay used to have something to do with the ARISTCRAT JUBILEE people from England. They branded the machines themselves after purchasing the base stock from the UK. That pokie, all fully restored, would fetch between $1200 to $1500 from a collector.
Be extremely careful how you clean the score reels/ damp cloth only, no chemicals at all. Also, look up a resto site on how to oil n lubricate the entire machine. You just cant use any type of machine oil or you will cause major problems.
There will be a date stamp inside the machine on the metal chasis somewhere which will give u a date of build. You will have to look very carefully for it. I reckon it shld be on the right side somewhere usually.
Well done on a great pick up.
