I have for sale a Nikon Nikkor-M 450mm f/9 lens in a Copal #3 shutter. Serial #76410. This lens has been handled carefully, and is in near mint condition. There are absolutely no scratches or dings anywhere on either the glass or the body. The optics are pristine. It is practically indistinguishable from new. One of these went for $450 on ebay last week, and that is the price I am asking.
