this very hard to find Postal weights exist in 15 and 40 gram. They made 
5.872 of the 15 gram weights &
15.433 of the 40 gram weights

But also if so much from them are made.... not to find ! The owner ( German Post ) never sold them to other persons.

First decree 17. August 1868
Official decree 27. December 1884

The END for this nice weights toke a long time.

I have only this 40 gram postal weight. Mark on the knob: Precision star, mark on the body:
