I'm going to answer because nobody else has.
Just the fact that the shaft has "Schon" in script means it was made about 1995 or later.
The best way to date it is to identify the exact model from what series, then find out when they were sold from there.
Just looking at your cue, it looks like an SL-2 from somewhere around 1996 - 2000 or so. That would be my best guess.
This is based on the appearance. It could also be an STL 4, in which case it was made at a more recent date.
