Vaguely related question: I have a Nikon MD-14 motor drive minus battery tray. Was the same tray used on other Nikon MDs?

It came bundled with a Pentax Winder ME (which I had a battery door for and wanted to go with my mint black ME), now quite tempted to find a Nikon FG to go with it rather than leaving it in the bottom of the wardrobe.
