Yep, you're gonna pay for that one ...
I got a privately printed exact facsimile copy (hardcover and all, but less quality paper used for the pages) from a 4th FG guy a few years ago - much cheaper, but it's not available anywhere. It's Grover Hall's earlier version of
1000 Destroyed. If you have one, you pretty much have the other in terms of content, though there are slight differences. Good to have both if you can afford it.
"Tettley", by the way, is a combination of the names of the primary landowners upon whose farmland Debden was built: Tetlow and Kettley. In my preparations for touring DB in 2002 (see my site for Then and Now pics/tour), I was put in contact with Tetlow's son, who still lives near the 'drome. He told me "officially" that yes, "Tettley" was a combination of the two names.
Tetlow also took me out to the exact site of Don Gentile's "prang". On the drive back, he said, "See that pond?" "Yes". "That's the famous pond where Gentile's plane is supposed to be ... it ain't there!"
That evidence, along with interviews I had earlier conducted with maintenance folks who worked in the 4th's so-called "heavy maintenance" squadron ("We never had a pond or anywhere else we 'dumped' aircraft parts.") cinched it for me.
Case closed!

PS: One day I'll put my copy of
Escort to Berlin up for auction. Signed over the years by many 4th FG alums, including Blakeslee, Goodson, Pisanos, Don Allen (famous nose artist), Edith (Gentile's sister), etc, etc.
