This is the only photo I have of my grandfather in uniform. It was taken 1917-18, and he is the man on the right. It appears to me, the man on the left is an officer. Can anyone identify the branch of service it might have been? He was born in 1895, in Luneburg, Germany, which is in Lower Saxony. A City Register record from his hometown lists him in the following towns: Bleckede (Aug-Nov 1914) & Geesthacht (Feb-Apr 1915). Both of these towns are located on the Elbe river. Does anyone know of any military connection? I would appreciate any insights, comments about these uniforms and where I might find personnel records. No luck with it so far, and I have heard over the years that many of these German records were lost. . .
Thank you for any help,
Leah
