Planemike got there first!
Tredigraph, your are quite right it is a pic from the Morris book “Two men in a Flying Machine”, which I have just re-read. Recomended.
An up to date pic...
While we are in "recommending mode".... The April 2007 edition of FLYPAST contains a six page article on GENAIRCO. Apparently John Morris's
son Charlie flew VH-UOD after it had been restored.....as per above image.
