I recently bought an Arriflex 2C and noticed something was missing inside the door. I have three pictures below.
Pic 1: This is from a YouTube video. There’s a part in the blue square that my camera doesn’t have.
Pic 2: My camera.
Pic 3: This is from a manual. There’s no part there, but a plate is screwed in there.
Does anyone know what this part is and what it does and why it’s not in every Arri 2C?
