I see on the UK English the barcode is 3307210409393. On the back there is a "Watch LOST on Sky" logo, and a "ask about games.com" logo. It also has UK address.
I find this one is missing those two logos, and found the matching barcode. It has France address.
Here is one with a Greek label, but I do not think it is an official label:

Or put [UK] on the old one and not have a TLD on the new entry?
It is likely that this 423 had import labels on the outer shrinkwrap of sealed copies that would be able to pinpoint specific releases. An un-sealed game like this can be difficult.
