Newbie here say hello to everybody. I do need some kind of help from expert like you.
I got a box of old camera parts last year and I can not figure it out what is this for. Try google for days, no luck. I suspect these masks probably for some kind of focusing device. It will be highly appreciated If you can let me know what are these for. thanks in advance.
There is "insert mask with pin toward lens" indicated on the leather surface.
