Hello, fellow shadows stalkers !
I'm back, to thank all those who helped me on my quest about Johann SCHRETTEGGER. That's quite incredible, this sum of knowledges all around the world ! It's becoming an evidence that thematical mailing lists are the second encyclopaedia for every student, in every subject ! Special thank to Hester HIGTON, Robert H.Van GENT, Reinhold KRIEGLER and Karlheinz SCHALDACH
