Mmmm ...
.. Masling Rotor & Wing. I have a feeling they used to be the Aussie Hughes distributor?
I seem to remember REX Aviation being the Hughes distributor ... but then it was so long ago .... I could be wrong
Whatever .... somewhere in the attic I have some pics of VH-FJC on duty at Thursday Island in the Torres Straits '78-80 .... I shall try to get my act together!!
