I have attached this photo of a Yellow Express R600 Flintstone Mack that I saw in West Wollongong around 1970. [Can we use the side view picture if we are only using one?] The side view of the Mack shows its somewhat unusual turntable being used at the time. I have been told that it is a Bollard turntable of French design, that utilised two steel wheels connected to the float and a bollard secured to a plate on the prime mover 

Also just regarding issue #39 Page 10, I enjoyed the excellent story, Aussi
