[Illustration: FIGURE 243]
The center piece applied to this cast-brass plate with wire fasteners
bears an early form of the arms of the State of Ohio.[142] The plate
proper has holes in it other than those needed to apply the present
device, which indicates that it was a stock part, or possibly that the
present center device is not original to the plate.
[Footnote 142: For an interesting discussion of the evolution of the
arms of Ohio see PREBLE, pp. 639-642.]
