Terry -
Volume IV has four deck views from Capetown (or Luanda, Angola) and reports these as the only photos in existence in 1983.
1. Semmes and Kell.
2. Kell.
3. Armstrong and Sinclair.
4. Anderson (?) and unknown.
Are the two photos in Singapore the same picture, or different views taken seconds or minutes apart? Are they possibly a pair of stereo views?
