The Scovill Waterbury Lens
is a single achromat (hence the name). Having only two elements in
one group in the rear of the lens, it was the most inexpensive lens
offered in their catalogs.
Early in its run,
Waterbury Lens Variation 1 had round Waterhouse stops that were
inserted from the front, and held in place by a wire spring clip.
By about 1885,
Waterbury Lens Variation 2 had a rotating wheel having four
stops, and this is its most common form. Occasionally, it will be
found with an accompanying
Elite
Shutter, which was designed and marketed by Scovill to fit the
Waterbury Lens. References:
