This example of Schalenblende with galena and pyrite/marcasite (a one side cut but not polished specimen) was found by myself in the late 1980s in the area of the former main shaft and processing plant of the Breinigerberg Mine immediately northwest of the road from Breinigerberg to Stolberg-Nachtigällchen when a short time excavation was done.
