Good to know, I may have to add that one to my own library. I also love the accounts of daily life in the various air services of WWI.
I do not have a copy of "Canada's Fighting Airmen", not yet. I've run across several examples over the years, in various conditions. Prices here seem to range between $20 to $35 and when I find a nice, clean 1st edition I do intend to grab it. The price of that signed edition is a bit too steep for me as well, but thanks for letting me know about it - much appreciated.
