The NN pony on the left is at least 1/8" shorther than the N.W. & B.I.T. Co to the right. The NN has a wonderful graphite spiral wound about the upper half. The color for both pieces is correct. The back skirt of the NW & BIT has no markings of any kind. The NN was formerly in the collection of Ruth and Floyd Kidder. The NW & BIT was in the collection of Gene Condon.
