hardware is also distinctive because you can look from one side of the lure
to the other through the 'see-through' hardware hole. It's one of the
very few lures with this feature.
Early c. 1904 hardware with 'gem-clip' has an attachment through the
eye of the hook which is vertical to the long axis of the lure.
Note the small glass eye with the tiny pupil and 'egg-yolk' color to the
eye, the gills are thin and 'sweep' up between the cup and the eye.
The forehead is more peaked and referred to as "high-forehead".
Later c. 1912 hardware with the 'flat-plate' attachment through the
eye of the hook is horizontal to the long axis of the lure. Note the
glass eye has changed with a larger pupil, and the gill marks are thicker
and shorter. The forehead is more rounded.
