Answered near enough to gather in the chocolate fish.
You have been looking at the top of the nose cowling for the Cessna 150F ZK-TEO , c/n 150F-61540.
This airframe arrived in NZ in a damaged state and was rebuilt at Aeromative Overhauls and became ZK-TEO on 03-02-1986 with B T Hvid and T H Kendrick. On 10-04-1987 it was relisted to the Wairarapa & Ruahine Aero Club until moving south to a strip just north of Hokitika with R G Cook from 19-06-91.
As the man said. It has a Lycoming O-320 of 150hp.
I was also looking for comment on its Horton Stol conversion and the name "Bushhawk".But I will pay on what has been provided by "cessna185".
Now then cessna185, do you want the fish sent to you by snail mail or will you be at NZMS for a formal hand over ?
