Notes: 

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.
