Great pics! I too have a German grandfather (the clue's in the name) but no pics to share, unfortunately. He served in WW1 but was already too old for WW2.
Also had an great-uncle who was a general in the wehrmacht and another cousin-once-removed who was a u-boot captain. After the war, he rose to the rank of admiral in the Kriegsmarine and had use of a Wessex at Portsmouth! We visited him sometime in the sixties when he was there, presumably on some sort of NATO detachment.
Another uncle deserted from the eastern front and became a successful German diplomat in the Lebanon, USA and Canada. I only wish I had quizzed them more while they were still around!
