This is what she has sent (it was quick - she must have been asked before).
She says the Serial number is 120837 001998 and the front of the tag says R (in a circle) then under that GUCCI and under that made in Italy.
(I hope the photos come up alright as I had to reduce them from the email ones she sent)
The photos are still too blurry. Maybe suggest the seller to use macro setting (flower button) and take photos with no zoom and lots of light to get clear, close-up photos.
