Nikkor Micro 55mm 2.8 Ais lens in "For parts or not working" condition...it looks nice and clean, hopefully it just has a stiff focus ring...
For under $50USD its not that bad a gamble...another attempt on my part to rescue an unused lens...
They are not that difficult to get into* - though I'd buy a set of JIS screwdrivers if you haven't already done so. See if someone has one on Youtube as it's long enough since I did mine that I doubt I can provide much help.
*Or get back together again!
