Got the following from the horse's mouth as far as the MLGB sticker is concerned.
Very straight forward - the number includes the year of manufacture and then simply a sequential serial number - different for each item.
This is actually exactly the same system we use at our company - QC then had a record of which serial number labels (ie numbers) were used each day and on which line, shift and operator, so if there ever was a manufacturing problem it could be traced back to a day and a particular production line and shift.
