Good stuff Dan.
My material came from Mark Davis. I stayed with Mark and Marianne Davis last weekend, while in QLD for the Aussie Q Scale Sprintcar Titles.The material originally came from Richard Anderson, who was hugely into Q Scale, in Queensland, over 20 years ago. He was the 1994 Australian 1/4 Scale Sprintcar Champion!
Mark brought Richard along to the track on Saturday and I managed to sit down with him for about 45 minutes and listen to the tales of Q Scale from back in the day.....including buying and sourcing goods from the 'States, before the internet! One needed to be ultra keen to get that to happen. Hey... it seemed like shipping to Australia was easy back then....

Richard said he owned many cars and was mentioning names New Era, Delara, WCM, Pheonix, and many more, including a couple of Conley's. At this stage my brain was starting to hurt!!!! He eventually sold the lot and they are all floating around Australia somewhere, waiting to be rediscovered.
I was also given some material on Delara that will go up at some stage soon.
