Hello everyone, I recently got an older Cambo recessed lensboard and when I tighten the retaining ring it won't let me adjust the aperture scale. I tried two different lenses on it just to be safe, and there looks to be that the front of the lensboard isn't completely flat like a regular board, there is a small diameter around the hole that sits lower than the rest of the board which when tightened, won't allow for aperture adjustments. Is there a way around this or should I return the board and get a newer one? I've attached a picture and tried to describe it as best as I could, any advice is greatly appreciated.
