I have the answer for you, Gordon.
Out and about in Lincolnshire this week, I found a bookshop which had a few of these titles on display. Inside the front cover, they carry a full listing of the series up to that point ie #60 carried details of all 59 previous titles.
Unfortunately, I was too tight-fisted to buy #60 and scan it here (
) but if you can get hold of a high-numbered
'Airfield Focus' you'll have your list.....
