Greetings, I'm new here so I'm not sure if this is the correct thread for this.

Anyways, I recently bought a Japanese Rokuohsha Ohca and it came with a attachment for sheet film and another that I believe holds dry plates. But I'm troubled because this attachment has a slit on the top for... Something?

I asked Claude a.i. what it's use could be for, but it was having issues telling what it was looking at. Said it was for a "light shield" if that's what it's called, but there's already one to the front of this attachment. it also said it could've had felt lining that aged and fell off, but there isn't old adhesive on the inside.

a little clueless what this gap is for and if something is missing. if anyone knows please let me know.
