As a follow up I reread the great article by J.C Munnell in the Autumn, 2013 DGJ. The Grundig over-and-under rifle he describes is remarkably similar to the Loesche. In addition to the unusual cocking indicators that POP UP when the barrels are fired and the "front only" set trigger, he mentions that the action is a Roux. Is there any historical information on this action?
