Multi convertible convertible, currently comprising of two 18 7/8" cells, which combined makes a 10 13/16" (270mm) lens. Front and rear groups alone will provide different focal lengths, and other cells of this generation may be combined (no other cells other then those photographed are included).

Covers 8X10 at infinity, much more with the single front or rear cells.

Glass is generally clean, but does have some minor dust/coating marks/surface marks as to be expected from a 100 year old lens, none of which affect image quality.
Shutter fires on all speeds.
