the numbers do follow some rules, Heather of PlaymoDb is the authority here on this, e.g. all fat klikies have certain front numbers etc but I think not so specific that you can decipher what each part is for unless Geobra had planned it this way right from the start....and probably requiring a 10 digit number

do continue to bug us...if we know, we'll be glad to help....good exercise to stave off memory loss ..speaking for myself
