I worked at the Browning Gunsmithing facility in St. Louis for several years, bowling pin finish is exactly what I called their thick poly finish. While it did give Browning's guns a deluxe appearance it was difficult to work with because of the tendancy to crack and chip. The refinishers had a devil of a time with it chipping when they used an exacto knife to remove the masking tape from the checkering after refinishing.
