Found these whilst rummaging in the old shoe box.
Below we have a photograph from the CMM collection showing ZK-CNG at the end of its ag flying days, still wearing the Aerial Sowing tag, and parked outside the old Canterbury Aero Club building at Christchurch in September of 1973 - awaiting conversion to tow plane configuration.
Below is Auckland Gliding Club Piper PA-25-235 Pawnee ZK-CEB (c/n 2421). Previously an ag machine with Rangitikei Air Services from 1964. It joined the Auckland Club in October of 1967. Pic taken at Drury 15-03-2009. Note the four blade prop. (ZK-CNG had one for a while as well).
Below is a view of that prop being worked on.
Below we have an Andy Heap shot showing ZK-CEB towing ZK-GAK, GXF and GNO on 30-04-2011.
Below is another fine shot from the CMM collection showing ZK-BWP ready for work.
