i came across such a lens .. I have no idea about the quality of such . It has two cemnted elements in front and two in the rear. he brassbarrel measures 1 1/2 in. on the front and 1 3/4 in rear. It should cover 4 x 5 .

sounds like Zeiss Protar Satz-Anastigmat, so look for information for that lens. Should be a decent performer if it's condition is right.
