'By George' Yes I was there in '79, Executive Air Maint then or Forrester Stephens as you say (VH-BOB came there I think?), taken over by H.C. Sleigh I believe (Golden Fleece?) after I left. It probably was the N22 as the Searchmaster like you say, they looked the same to me when I was a young whiper snipper
I mainly worked on IO540E1B5 piston engine O/Haul but the Nomad sure had a lot of people fuss over it with many a comment, good & bad.
Recall B. McG flying them too?
