Rob de Bie has an excellent website on the Me 163.  This can be found at:
 http://www.sml.lr.tudelft.nl/~home/rob/me163.htm 
He has an extensive collection of photos of existing Me 163's in museums around the world.  There is a listing of individual Me 163's by Werknummer and Stammkennzeichen.  A list of 7 archives containing material on the Me 163 is given, including links to 6 of them.
The links section is outstanding, as I was completely unaware that there were this huge number of sites just on this one aircraft!
For Me 163 enthusiasts, this site is a goldmine.
Regards,
Richard
