Once again, that the buckle was put on one of the sites. And I was interested to learn about it more.
Now with the help of colleagues, I know that it was assembled from two different parts.
Box from Berge & Nolte. Roundel made by ST&L.
I wanted to find the truth.
Maybe it was not understanding because of the complexity of the translation, thank you for your attention.
P.S. It is a pity that it can't find the original roundel.
