I would give the old TCR number to the chip on the right because it is a H&C(LCV) (long cane variety.) This is a Burt Co. mold which is older than the chip on the left, which is a Paulson H&C(SCV) (short cane variety.) As long as we make these, two different chips, the other differences are incidental. The easiest way to tell the cane length is that the short canes touch the brim and the long canes do not.
