Switzerland - Different Sitzende Helvetia

I try to identify my "Sitzende Helvetia". I have a Michel Mitteleuropa 2016 and an old Zumstein Europa 1981 (German language is not my strong point).
It seems there are there different periods, all of them with K 11 3/4:
- 1862 - white paper with control-mark 1
- 1867 - white paper with control-mark 1 (different colors and values)
- 1881 - fiber paper with control-mark.
In Zumstein I found for 1881 - blue and red fibered paper (identified on my stamps).
Still I cannot say that I can clearly identify these 3 different periods on identical values and colors, especially on used hinged stamps.
A good example is 50c used stamp. The date is 12.12.81. The paper, in my opinion, is more yellowish, and rather thin but the control mark is visible. I can see the red and blue fibers in the paper using a basic digital microscope. In Michel there is no information about blue and red fibres for 1881.

How can I easier identity these 3 different years of Sitzende Helvetia?
Thanks for your answers!

You seem to have the basic differences between the issues listed. If the stamp paper exhibits fragments of blue and red silk threads, then it is the 1881 issue. The other issues were printed on white wove paper. The difference between the 1862 and 1867 issues are the denominations and color. I don't see any similar colors (for the same denomination) that may lead to confusion. I'm looking at the Scott Classic Specialized Catalogue.
