Double checked the photo I downloaded and I have to correct my info about the Denon J-card number.
On the photo there is a tiny fraction of a red colour visible so they probably put the Denon front and Philips inside on the same photo. Hence, not related to eachother.
About J-card numbers...
I've started to register those numbers of Philips and sisters tapes in an Excel sheet.
There are so many differences with the 3104 106 numbers, especially with the 1st serie
