In the picture of the Pathe label at https://www.ebay.com/itm/78rpm-MAURICE-RENAUD-sings-TANNHAUSER-ROMANCE-ETCHED-PATHE-Paris-1903/253050292232?hash=item3aeaf90808:g:91EAAOSwKRJZbPuq can anyone explain the significance of the "12" at the twelve o'clock position and of "11834" at the six o'clock position? I've looked unsuccessfully in Girard and Barnes for the answer. FWIW, I'm not planning to bid on this item, nor do I have any connection with the seller. I'm just using the link as an easily-accessible example of numbers on Pathe discs that have puzzled me. Thanks.
