I've seen the HE-111 at Cavanaugh, and like the aircraft that crashed, it's also a Spanish built CASA aircraft with Rolls Royce power plants I believe (not Jumos). I've heard that most of the CASA built aircraft were powered by Rolls Royce engines (not sure if they're British Rolls or license built Rolls, any corrections are welcome on this).
Cavanaugh Flight Museum has great restoration facilities, and I believe their intent is to make this aircraft flyable. When I last saw it, is was still not flyable, but otherwise in very good condition.
