This is a Nikon MF-15 data back for the Nikon FG. The outer box is damaged, hence the "scratches" designation, but the contents are complete and the back itself is in excellent condition. The included battery is original and likely unusable. Power and the buzzer were confirmed to work with a different battery. Operation with the camera body attached has not been confirmed. As a bonus, I will include new batteries (LR44 x 2) separately from the second photo.
