Operated by the Diamond International Corporation. It was noted in a hangar in Mexico City's Atizapan airport in Oct 2015 registered to a private owner as XB-OIQ, but it was not known if it was still airworthy.
Taken a short while after I had flown in on it (on a scheduled passenger flight) from Birmingham. It was a single pilot operation and I got to sit on the right hand seat in the front office. Aircraft with Air Anglia from Nov 77 to Nov 80, when it went to Eastern Airways.
