JB are the initials of Jean Billon. This Swiss company is normally a retailer, but sometimes makes complete boxes under the name Jean Billon-Haller (Billon and his wife Haller). He works also in partnership with Isaac, and it is not rare to find on the bottom of bedplates the mark SBI for "Société Billon Isaac." I have seen that on many Paillard music boxes.
