Yes - Cessna A185F ZK-JNH3 (c/n 185-03177) really does exist. This ex Swedish aircraft was registered three years ago on 15-09-2008 to Bruce Drake of Rangiora.
I spied it at Bruce's Fernside hangar on 09-09-2011 awaiting a decision on its colour scheme.
Bruce has his own very descriptive phonetic language. In this case JNH = Just Not Happening.
