You're
halfway right....
There were
22 airframes built, even if only 20 of them flew.
There was one in Toulouse, used for static (structural) tests, and vibration tests, and suchlike, and the one at Farnborough, used for heat and stress cycling.
Neither of them survived. It seems a few sections of '0001' still exist somewhere at Toulouse, and a few sections of '0002' are still on display at the Brooklands (UK) museum.
I have no idea whether either actually had space models of the engines in place, or simply representative ballast weights.

(I made up the '0001' and '0002' designations.... maybe somebody here can still remember what those 'static' airframes were referred to formally at the time?).
