I too was intrigued as I too cannot remember seeing them on any B707 I worked. Looking closely at the instruments they all say TEMP on the face of the dial. I can see too they are grouped in pairs, the top and bottom one the same, the centre two the same, probably 1 and 4 tank temp and 2 and 3 tank temp, fascinating nonetheless. Keep safe, Terry
