Experts, I want to share with you my find, this is a cockade of rank and file RAD. I managed to find this cockade when dismantling the old house, apparently during the second world war German soldiers lived in it.
*The Imperial Labor Service (Reichsarbeitsdienst, RAD) is a national socialist organization that existed in the Third Reich in 1933-1945.
