That should be a bus from my home Dortmund (Germany). Does anyone knowing the serial nr.? It mus be something like "WMA79500xxB00xxxx". Or could someone have a look around the bus if there is to see his former number which must have been 1411? The original numbers have been placed in the front above the headlights, at the end on the top, on the left side under the drivers window and on the right side next to the first wheel (left side of it). Thanks for any help to get the information, if this bus is the one shown at this foto here: http://chang.ch.funpic.de/index.php?menu=6&id_kom=236

The serial number is WMA7950052B005597
And thank you for your help.

That is great, thank You! The serial number is right, it is the number 1411 from Dortmund!
