CANBERRA WV787 Biological Warfare research aircraft

Does anyone have any memories of the Canberra WV787, an aircraft used
by the MoA as an Icing Tanker Aircraft, and by the Army Department of
the MOD as a Biological Warfare research aircraft. For the last 7
years I have been researching Porton Downs' BW experiments held in
public areas of the UK. The relevant BW trials documents are now in
the public domain.
This aircraft was involved in disseminating massive amounts oflive
bacteria during trials at Tarrant Rushton during 1967. The bacteria
used was E.coli and Bacillus subtilis.
I do realise that this aircraft is now being preserved at Newark Air
Museum.
I would be grateful for any information regarding this unique
aircraft.
