Hello

I bought a Grado RA-1 on ebay 4 months ago. It was of course used, and the seller claimed it was only 3 months old, at the time.
He did however not include any papers, or the original pizzaboks, so now I started to wonder, how old this unit really is.
There´s written a possibel serialnumber (11047) on the bottom plate.
Is it possibel to determine from the serial number, how old it is?
It does work perfectly though, so I´m just curious
