Hello Uwe,Hallo Rüdiger - this is looking very good
Is it possible to show us such a brass rivet with a close-up photo?
and off course the question if you make them, how you make them or where did you buy them?![]()
these are round-head rivets from Knupfer with a diameter of 0.6 mm and a head size of 0.8 mm. Here is the link (https://knupfer.info/shop/index.php/nieten-nietenschrauben/feinnieten-halbrundkopf/n-g-06.html)

Greetings
Rüdiger
