Dear All,
I am sorry that my German is appalling, but I hope that someone can help me in English!
I am currently working on a paper describing the microscopic characteristics of the first series of Baden stamps:

I am particularly interested in impurities: for example, the inclusion of different coloured fibres, and grains of undissolved dye in the paper, as these appear to be very distinct between different issues, reprints, forgeries, and even printings of the same issue. However, I have found no information about these details published in English... but my German is too poor for me to find information in that language!
Does anyone know of published descriptions of these microscopic characters?
Many thanks,
Joe
