Nikon Microscope Objective CF Plan 50x0.8 WD 0.54. Unable to use this as I never got the microscope I wanted but it looks to be in good condition apart from some the painted writing on the barrel has worn off. From what I found out CF means chromatic aberation free, BD means bright & dark field and WD means working distance.
