That one looks like being worth chasing but this is all I could find on my usual book source
I went to Amazon and they have it free as an audio book (with membership) and reasonably priced as softcover. I do not like the hardcover price. Greg Boeser - your thoughts on it as an audio book please. I expect the actual book has a number of photos that make it a far better option.
I had not known that he was such a prolific author.
Found it on ebay for $28. It's only a small book at 74 pages, but it fills a hole in my RAAF unit history collection. The John Lever book looks good, I have a few of his titles.
