I found a copy of "Wings" by H C Biard in the National Library in Canberra and arranged to borrow it through my local library. I found it to be a very interesting account of the early days of Aviation in the UK.
I will certainly add a copy to my Aviation collection if/when a copy turns up for sale.
If anyone in Oz is interested in reading it, see your local library and see if they will borrow it for you.
