The houses are Coniston Ave over Campbell Park Rd and Windermere Cres going off towards the Slag Heap.
If you look closely there is a 'dot' ontop of the Heap which was a Cylinderical thick steel container with a door & a slot for looking out. It might have been leftover from WW2 where military viewed the skies for German Bombers?
As young lads me & my mates saw it & it was 4 or 5ft diameter & maybe 7 or 8 ft tall.
