It's my understanding that all the Christie & Jones Chips, including the TH&C, were made by the Burt Co for them, & Burt also made the Paulson TH&C's as well, until approx the early-mid 1970's, when Paulson created their own manufacturing system .. & that from ' at least ' the 1950's onward to the 1970's, , essentially all clay chips ( that weren't TRK ) were made by Burt Co , regardless of what the box said ( "Mfgrd by Marion & Co, Mfgrd by Christie & Jones" ect ..)
Is this essentially correct, & were the Jack Todd chips also Burt produced?
