Today I received the kompas. Looks good, thank you. Do you have a specification story how to use the kompas?

Hello, 
I am glad you received the proportional compas and that you are happy with it.
Several books (in french) have been edited in the 17th and 18th centuries on how to make use of this "mathematical instrument". The most famous is from: 
Jacques OZANAM (1640-1718)
L'usage du compas de proportion
