Hi can anyone tell me the name of these rubber rings and what is their function on a camera? I've inherited a large collection of vintage photography equipment and I'm uncertain about the uses for some of the items.

Rubber lens hoods?

Think you that's what I thought but I wasn't sure about the rubber. Do you know if these are universal or for a specific type of camera? They don't appear to have markings.

If that's what they are(?), they're lens-specific to its filter size, e.g., 55mm or whatever. Do they have threaded male rings?
