Mine definitely says 120V 60Hz 1.1A on the back plate.  Made in 
Korea, FCC ID A7R9K2PC-4A.  No mention of Amstrad UK, but rather 
Amstrad International (USA) Inc., 3202 Doolittle Drive, Northbrook, 
IL, 60062.  The curious thing is that the label refers to it as a 
"monitor".  No reference to it being a computer of any sort.

Yes, but that's useless if what you want to do is boot from a 720K 
and have 2x720K of floppy storage online.
