Notes:  Judging from the number of these lenses in the U.S., they must have been rather popular - surprisingly so, since E. & H.T. Anthony seems to have had an exclusive contract with Dallmeyer (London, England) as the only non-EA-lens sold, and Scovill seems to have only carried their Morrison brand as a wide-angle.  Most, if not all, appear to be marked "B.F.&Co." to indicate that they were imported by Benjamin French & Co., Boston.  The levers control which of three f-stops or wide open is placed in the optical path.
