I am preparing to buy the EL-Nikkor enlarger lens 5.6/80mm for UV photography, but I have found old models with a black/chrome body with different serial numbers. Serial numbers include 988161808005, and 962207 (links included). Are any of these suitable, or is one serial number preferable? Thank you for you help!
