What does this lensboard fit?

I have a nicely finished board for a Copal 3 shutter with no useful
identification markings. It's metal and measures 4-inches square
and about 1/8-inch thick. There's a fine fine ridge that runs just
inside the edge of the back, along with the number 105822 cast
into it.

Does anyone know what camera this fits?

Thank you.

Steve
