Ringfoot Fount Lamp
below show the difference between the more common 0153 Alacite fount and the
0153A ringfoot fount.
The lamp to the
left is the Alacite "Ringfoot" fount. Note that there is
no metal burner collar on the ringfoot fount. The burner screws into
glass threads molded into the lamp, while the burner on the 0153 screws
into a metal collar and thread assembly. Also note the broader, flatter
shoulder on the ringfoot lamp just beneath the oil fill assembly.
The shoulder on the 0153 in more rounded and pronounced.
The difference between
the bottoms of these founts is quite apparent. Again the Ringfoot
lamp is to the left, and you can see the pronounced "ring"
from which it derives it's name. The 0153 lamp to the right has wider
solid bottom with three small feet.
