One board has an opening for a Copal 0 shutter and has a small hole drilled for a quick release cable socket, but is taped over. The second has an opening for a Copal 1 shutter.
Yes, these fit the folding metal field cameras made by Toyo and have smaller dimensions than the boards for Toyo monorail cameras.
I do have one Toyo board for your camera that has an opening for a Copal 0 shutter, and a Xenophon gelatin filter holder mounted on the back. I'm asking $25 + shipping.
