The Germans occupied the Krmelj in April 1941. During this first German occupation, the post office operated. They used an old one-line KARMEL seal and a newly made German two-circle KARMEL (STEIERM) postmark with counter code A. On October 8, 1941, the Germans left Krmelj to the Italians. The post office continued to operate until the late summer of 1942, when it was closed. It was reopened on January 1, 1943, until August 14, 1943, when it was finally closed. The Italian administration used a two-circle Italian postmark with the inscription KRMELJ / (LUBIANA). During the second German occupation (autumn 1943 - May 1945), the post office Krmelj remained closed.
German two-circle KARMEL (STEIERM) postmark with counter code A used on 4.8.41 during the first German occupation. Very rare.
