I have available a 210mm APO EL-Nikkor lens. It is in excellent condition with no blemishes on the glass and very little on the barrel. There are some spots with tape residue on the barrel and that is about it. The aperture moves smoothly through its range of f/5.6-32 with solid click stops at each aperture. The coatings are excellent. It comes with the original mounting flange, and a front lens cap. It does not have a rear cap, but I will tape a metal cap on the back for shipping to protect the glass. This was used in a studio on a 4x5 camera for flat art reproduction using a scanning back, but it works incredibly well for enlarging. I am asking $5400. Free shipping within the US, actual shipping to Canada, the EU, or Australia. I will not ship to Asia, Africa, or S. America due to the high rate of fraud. If you live in those areas, arrange with a friend in the US to have it shipped through them. I will work with you as best as I can. I would prefer to keep this to a money order if possible, but I can take Paypal or Google payments.
