Dave,
All this rascal shows on the label on the back of the set is the model number, 
serial number and a square sticker that shows S20 along with another sticker 
giving the date of manufacture (July 2003).  It also says made in China and has 
another sticker on the top portion of the back that says "imported".  What a 
novel idea, I wonder what was their first clue :-).
