Crikey, Norman if I knew you were in the group I would have! Just got the book on Thursday. You list the 6 May claim as an aircraft of Jasta 20, but I have read that Jasta 20 didn't have any tripes at that time.
Really enjoyed the bios of all the flight commanders and interesting others in 40.74 and 85 Squadrons. Quite took me back to the time I read
Norman Macmillans "Into the Blue" which along with "Tiger Squadron" kinda got me started with what my wife tells me is an obsession....unlike buying more shoes!
