In 1972 I was given a brown jacket from my grandmothers neighbor in Wangen, Alsace. Becuase it is extremely small (fits a 10-11 year old) I assumed it was HJ/DJ. It has no patches or shouldar board; only remnants of red thread on the left arm. It has smooth silver metal buttons. They along with the belt hooks are RZM stamped. Did DJ/HJ ever have smooth metal buttons?
