Well that is a great thing to do for the guy's family. I haven't read all posts (night shift and I am very tired) so this might have already been mentioned but something similar happened recently with a Jap flag captured and brought home as a souvenir. It was signed by the Japanese soldier's family and it really meant something to them to get it back.

This gives me an idea. I have a picture post card of a German soldier....I wonder if I can locate his family to send it to.
