I said B&G as in they used the BJ mold when they took over (and use it currently in europe with the BG monogram) I was too tired to look up the catalog last night.

Yes your chip was produced by BJ (and not RT, which answers your original question )

Purists will no doubt always refer to the mold as 'BJ'. I go along with that. No doubt GPI will want them all called 'GPI' soon
