The front is common to all 3 focal lengths and should have 3 scales on the Copal 3 shutter. You then get the focal length you want by screwing in the correct rear group. Looks like you're missing the 600 mm focal length...but that (as the other two) can be bought separately. Nikon also makes a 360/500/720 trio where the front group is common to all 3 focal lengths. Possibly the original purchaser didn't want a 600 mm focal length.
When I was 16 I thought my father the stupidest man in the world; when I reached 21, I was astounded by how much he had learned in just 5 years!

Hi Nikon does not longer produce LF lenses!Nikon also makes a 360/500/720 trio where the front group is common to all 3 focal lengths. Possibly the original purchaser didn't want a 600 mm focal length.
