Blue Bus has reminded me that we have another Cessna 120 registered in New Zealand, and has sent the photo below, taken at Rangiora on 17/5/14. I have therefore altered my previous post.
ZK-XTX (c/n 11759) was registered on 13/1/09 to FG Vernon of Queensland and ownership transferred to Kevin Langford of Rakaia on 22/11/13. It is easy to see that it is ex N77317, and before that it was NC77317. I believe it is currently inactive.
