This is the Photomic (non-AI mount) and works only on older F, F2 and Nikkormats. It does not work on any digital without modification (but it great on mirrorless with an adapter). What is "Nikkor-Q?". "Q" is for "Quat" and means four elements.
The lens is in good condition with moderate wear and works perfectly. There is a dent in the hood but it is only cosmetic, it does not affect the function of the lens. There is also a small cleaning mark on the rear element and a moderate amount of dust inside the lens but it will not affect your image quality.
