Featured Silver make up box

Hey folks, Happy Sunday

I need help with this quite heavy and beautiful make up box. There are quite a few marks. I see silver 900? Swedish import stamps? But there are other marks, would love to ID them. I rarely see silver 900, is it common? Maybe imported to Sweden from Czechoslovakia?
There is also a brand name inside of one item. Any ideas about that or is it later added?

It's approx. 154 grams in weight and diameter approx. 8,5 cm (3.3 inches).

Thank you in advance

 

well know cosmetics & scents...

 

The compact is refillable. The powder would have been chosen and added later.

A box like this is called a powder compact. It is charming.

It used to be common in quite a few countries, both in Europe and outside Europe.

The triangular mark looks a bit like the old Dutch dolphin mark for items below the legal fineness, but .900 is not below the Dutch legal fineness, and it isn't gold.
I do think it is a European mark, but the Czechoslovakian triangular marks are more 'filled in', with mountains at the bottom, the Slovak cross, and a number indicating the fineness.

 

A pretty purse accessory. It might well have had a matching refillable lipstick case.

Very pretty.
