Check the serial number of the back of your case, or as above see if you have the Music\Search option.
Though the serial number could be misleading if the ipod has been modified or refurbished! But I suppose if it isn't in working order to let you check the 'about' screen, that might be all you have to go on.
I think you can also judge from the firmware version number on the about screen (as well as the model number and the search function as previously mentioned).
