I understand that International Air Parts of Australia
http://www.intl-air-parts.com.au/front_page.html
have bought all the 748s and intend to restore them all to airworthy status except the series 1 G-BEJD which they intend to donate to Duxford as it is the last commercial airworthy series 1 in the world. Who flew her last sector. Stand up that now famous budgie pilot
.
The others are to be marketed worldwide but potential customers include UK based operations.
Be lucky

P.S. Highest time 748 is now c/n 1640 flying as C-GJVN over 62,000 hours. Good old Avro.
