This one was never solved conclusively on the yahoo group TramsDownUnder. I suspect just a few minutes, and top of head, for people here (so no prize, fizzy or otherwise).

7b?542 and? Scammell, Apr.66 (or maybe 1968)
...the truck beside is possible one of the work vans it definitely is not the Scammell.
...looks very much like an old ex army Ford or Chevy Blitz truck from the WW 2 era they were fairly common 1960s.
...Appears to have been remotored, - different radiator. Getting a lot less common towards the end of the 60s.
...Would this be the vehicle to which you refer? This one was a Scammell and was used by BCC to tow diesel/trolley buses when they broke down, as in this case in July 65.
...The breakdown wagon looks like a Blitz to me.
...No, I think it is the Scammell which is preserved at Ferny Grove, operating I believe.
...It isn't the Scammell but most likely the Ford Blitz welding truck; both vehicles now owned by Brisbane Tramway Museum.
There is a good photo of it in Last decade on p42 at New Farm Jn.
