Dan, that is a very interesting cloth Fliegerabzeichen. If Mr. Zeiger indeed had the badge for sale it could have only been between 1914 and 1918 since after the war Metz became french again until 1940. During the German occupation (1940 to 1944) the currency would have been RM = Reichsmark and not M = Mark. Based on the circumstantial evidence I say the cloth badge is a period item from 14/18. from: Wikipedia By the Treaty of Frankfurt of 1871, Metz became a German city, and was made a most important garrison and a strong fortress. Despite the departure of many inhabitants who fled to France to avoid living under German rule, Metz nonetheless expanded and transformed during the period of German rule. The fortifications on the south and east were levelled in 1898, securing space for growth and development. Some large neo-Romanesque buildings typical of the German empire appeared in the city. Following the armistice with Germany ending the First World War, the French army entered Metz in November 1918 to great cheering from the population, and the city was returned to France at the Treaty of Versailles in 1919. Metz was again annexed by Germany between 1940 and 1944 during the Second World War, and was liberated in November 1944 by the French and American armies. Regards, Hardy
