• All of the features of the previous, except:
• "MADE IN U.S.A." is now cast into the bed at the toe.
• A raised ring is cast into the bed to act as a receiver for the knob. This is to stem the splitting of the knob, about its base, which was a very common thing to occur. The high knobs were very prone to this, prior to the introduction of the raised ring, due to the greater leverage capable of being placed on them than could be placed on the low knobs.
