Hi Bernhard, welcome to the Club!
For a 93 instrument, the serial number should be roughly betwen 7,000 and 9,000. If you can check again, and post it here, we'll correct the thread title.
If you're looking to buy this second hand, please note that it may take a while before your request can be fulfilled. You could post some pictures here, as the Club usually jumps at the chance to make some educated guesses about the build details!
