His name was Hugo Scharli born in 1931 (that make him 81 if he is still around)
He was in a medical company (probably company 4 of army unit 1)
His address was : Ziegelfeldstrasse 2 Olten, Switzerland
I found the soilder for my K-31 tag, however he passed away in 2011. You might get lucky searching the swiss phone books online.
