Hi! I bought last year a NN3 MKII Starter Package. Unfortunately my camera was stolen. My camera had the camera mounting and the screw of my NN3. So I lost this part of my NN3.

I need to buy this part in the store, but I am confused, because I don't understand which accessory is correct.

I have this options:
  1. NN3 MKII Camera Mounting Knob and Square Washer

  2. Camera Mounting Plate CP2

  3. Rail Plate 3/8 inch

What is the correct accessory for my NN3? 1, 2 or 3? Or maybe other... Thank you!
