Just had a look with a torch at the back of it, there's 2 barcodes with 2 sets of numbers on each, some I think are customer support codes, there's also a number and barcode on a sticker attached to the VGA cable - none of em have A01 or A02 on the end
RE the quite a few months go thing, actually that reminds me of something the Dell guy said on the phone (after being bounced between customer support in india back to technical support then back again 3 times apparently no one knowing who is in charge of the monitor side of things rather than PCs), he said Scan bought it from them in October
