Notes: 

This is the distinctive Anthony lens with the conical shape.   It is usually advertised as the Single Combination Lens, although it is obviously a single achromat and what the combination aspect of it could be is a mystery.  It is typical of a single achromat in that it has a the full diameter of the objective is not useful for photography, and therefore a small stop or aperture is required to limit the off-axis rays from contributing to the image.  The cone tapers from the large diameter achromat to that small aperture.  Smaller apertures may be rotated into the lens with a wheel of stops.  The lens is capped by a metal lens cover, if it is still present.

The Single Combination Lens, like the Anthony Single View Lens Variation 4 was advertised separately from cameras, and often advertised at the same time as the other three variations were offered.  It apparently had a larger diameter of glass (for a given focal length) as Variation 2 and Variation 3, but not so large as Variation 4.  The larger diameter of the objective (and also the fixed stop), the faster working is the lens.
