Why is it that the magnification is never shown? Also some of these photos are colored - how?

Yeah, I agree with last comment that photos should have more info if possible.
wikipedia photos are more documented for equivalent....see http://en.wikipedia.org/wiki/F...
as an example

The first electron microscope to peer at an intact cell was a Siemens UM100  installed in the fall of 1942 at the Physics Laboratories of the Istituto Superiore di Sanità (the Italian National Institute of Health) in Rome.The subject of the first electron micrograph of a biological sample taken on November 27, 1942 was a an intact cell of the bacterium Leptospira acquatilis while electron micrographs of Rickettsia prowazeki were published  on the journal Rendiconti dell'Istituto Superiore di Sanità,6:298-304 (1943). To read more : Gianfranco Donelli, Electron microscopy at Istituto Superiore di Sanità (1942-1992):from Laboratori di Fisica to Laboratorio di Ultrastrutture ,Rome 2008.

 Magnification should always be indicated numerically or rather by a scale bar. Early microscopes did not print image data in the figure field and separate records were either lost or omitted at some point.
Electron micrographs are always grey-scale black and white images. They are, however, sometimes "pseudo"-colored by adding colors with, for instance, an image processing program afterwards for illustrational purposes.
