B&J recessed lens board?

[RoBBo]

Did they make these?
Does anyone make them now?
Help?
Need one for a #0 shutter, the more recessed the better.
The bellows on this 5x7 really don't like squishing in.

Some B&J cameras used a 4" square lensboard. These should be available on ebay for a price. Others used a 5.25" board. Rather than seek or make such a recessed board, I made an adapter to mount the 4" board on the larger camera.

What size is the board? I have a 4x4 inch recessed board with a Copal #0 opening.
