Wehrpass grouping - decorated WW1 veteran

Wehrpass and document grouping for Hans Bühl, from Erfurt, Germany. He was born in August 1898 and was  employed by the Reichsbahn (German national railway). Includes:

• 2nd edition Wehrpass, indicates that he served in WW1 from June 1917 to December 1918. He was awarded the Hindenburg Cross and an Austro-Hungarian service medal for his WW1 service. It’s also shown that he was awarded the SA sportsbadge in Bronze (SA Sportabzeichen im Bronze). He was trained to use the Gewehr 98k rifle. He was called up for service in 1937 and 1943, but doesn’t appear to have been asked to serve in the military. All entries and stamps have been photographed.
• Wehrpass protective cover, shows the expected wear and age, but isn’t fragile or damaged. See photos for details.
• Wehrpass-Notiz document, dated July 1940, indicates that Bühl was employed by the Reichsbahn (which likely exempted him from military service).
• Ausweis für Rentner (Pensioner card), appears to be post-WW2, shows the Bühl was receiving a pension from his former employer, the Deutsche Reichsbahn (he would have been living in the DDR / East Germany during this time period). 
• WW1 Militärpass ID booklet for Hans Bühl. He served with a fairly elite infantry unit, namely the Jäger Battalion (Kurhess) No. 11. He was recruited in June 1917 and saw service in Northern Italy and then in France (including fighting in the 2nd Battle of the Marne / the 1918 Spring Offensive). All entries and stamps have been photographed, interestingly two pages have been slightly damaged by fire at some point (which slightly obscures his service record, sadly). See photos for details.
