Only about 5% of the nickel plating remains, but the steel surface has a pleasant, smooth patina with no pitting. The pad is lignum vitae; the wrist handle is rosewood.
The spring keeping the crispy jaws together is so symmetrical I think it is original, but I have not seen another like it - the jaws have original grooves cast into the back to accommodate the exact shape of the spring. Maybe another jaw patent ? As with all the other alligator jaws in this series, the teeth interlock so as to keep them aligned.
