I'd like to see the chip that the 'recessed' image was taken from. That is the BetG mold, not chipco.
Chicpo only had two finishes in production. The slick are either slightly worn chips or another manufacturer with one possible exception.
During the six months of chipco's production Kendall did not have the $$ to buy raw materials (because you have to buy many years worth of most at a time) so he bought a load of blanks from Sunfly.
