This is a cool old time lens in working compound shutter.
Focal length is about 8.5 inches and coverage 5x7.
Shutter works fine at B, T, and time settings fine also, with the exception of 1 sec, which runs slow. Cable release fitting seems to be a larger thread than any that I have. An air bulb works fine with the time settings, but too hard to actuate B, T. I can supply and air bulb and tube if you need one for a low price. Includes mounting flange.
Glass is clear with a some marks on front and faint spotting on back. There is an optical flaw on one edge of the back element, see picture, lines at lower right.
