The last recorded order for arrowdies, in the Burt records was a December 22, 1967 order for the Fremont totaling 88,000 chips. See scan of inlay on the chips in this order.

The last entry in the Burt records concerning the arrowdie mold (no date on the entry) indicates the mold is NG and returned to owner. NG meaning worn out. This would have been after the 1967 delivery of arrowdies to the Fremont.

Either Precision Inc or Tommy Haines could have hot stamped the Pan chip as a sample to try and get the order and lost the order to CJ. A overstamp in a test run later.
