Luftwaffe Soldbuch of Flieger 'Arno Ziegler'. When individuals received their registration notice they were to report to the appropriate recruitment center where they would be issued a 'Wehrpaß', until they were inducted into active duty. From the autumn of 1939, when an individual was inducted into active military service the Wehrpaß was exchanged at the recruitment office for the 'Soldbuch' (Pay Book), which remained in the recipients possession as his official military identification document. The recruitment office would retain the Wehrpass and chronicle the individuals active service record in it. Arno was a member within the 'Lw.-Bau-Batl.4/XIII'. A few entries have been made, see photos. Nice original Soldbuch in very good condition!
