might be of interest to somebody. Can't find much reference to it, but I believe it was intended for a Leitz forensic comparison microscope, so long working distance. Could also explain why the vendor has 2 for sale. Magnification X2?

Some time ago I bought one of those Leitz Makro forensic comparison microscope lenses, the smaller one, with great hopes in its performace but I found it useless: it has very low magnification, very long working distance and it needs chromatic aberration correction at the eyepiece, so I can't use it in the microscope (too long parfocal distance) or in bellows (CA).

What intriges me is that I had seen those lenses mixed with photars and as I think the later ones don't need CA correction

No the Photars were designed to be used on their own without a corrective lens and not only on a microscope if so desired or for taking photos directly attached to a bellows. I am not sure if all Photars cover 4" X 5" film for their intended magnifications, but certainly many or most do. The newest Photars (last 3 of the Photar line) were I believe in the Leica Camera Leica R catalog (as opposed to the Leica Microscope Group) I believe until the Leica R lenses and cameras were discontinued in 2009. I have not checked to see if they are someplace on the Leica Camera website.
