Ah, yes, 2 DH-71s built, one went to Australia where it eventually crashed, the other was destroyed by bombing during the war. It seems there are two reproductions; one in the US has flown, while Mike Souch had one under way in conjunction with Nick Parkhouse, now with another owner. Looked to have been pretty complete a decade or two back.
Here's the next challenge, though I expect it won't last long...
