One old man: So, this guy is born @ 1870, goes into the army @ 1890, stays through three enlistments (+) and ends up (probably as an NCO), gets out before 1910, gets his nice civil service job, which he receives as an old vet and is in a war exempted occupation (trains/post office/forestry/etc.) and then joins the Luftschutz to do his bit say @ 1935-1945. being an older NCO he might well have been some sort of squad leader, training and leading a group of volunteer (HJ) firefighters etc. (pure speculation, but I have seen photos like this). He gets the KVkx as a geezer during some notable air raid incident. Interesting bar. Unless it's a fake. Personally I doubt it, but its not my bailiwick.
