The email address I used is as follows:
milmus@icon.co.za I explained what I was doing and asked nicely if they could supply me with some decent photos of the plane, so I could build the model as accurately as possible. About 2 weeks later I got an email back with several pictures attached. They enlarged to A4 size print without a problem and stayed clear.
Alternatively is ask the forum member MARS if he can get any decent pics. He is a member of the Gold Reef Scale Modellers. They meet at the Delville Wood Room, South African National Museum of Military History, Saxonwald, so I suspect he or one of the other club members knows the curator.
