G-ALHI, that would make it G-ASKA/G-MOSI, rebuilt by PPS in '71, which subsequently joined the Confeds and others, thence back to Blighty for Doug Arnold in '79. Another Trans-Atlantic ferry in '84 and now in the USAF Museum at Dayton. Sadly grounded.
Hadn't heard that story about Williams...
We want another Mossie!
