Hi Rhys,
The photo appears in Eoin Young's "Classic Racers" between pages 128-129, but it is quite a small copy, about 115 by 75 mm. This book was made up largely from articles Eoin wrote for NZ Classic Car, probably around 2000-2002 or earlier, and there may have been a bigger version in the magazine. Caption says Ohakea 1952, but I wouldn't be sure if that was correct.
