yes it does, it has a little piece that lights up red and iluminates the f/ stop. that is exactly it like in the link you posted.
could that be the problem ?? how could it be that Beseler made such a mistake, I bought this thing used, maybe it is not beseler's mistake, maybe that board is only meant to be used in B&W prints... I will try without that, but I'll be dammed if that's the problem. thank you so much.
Try putting a piece of electrical tape over the other end of the red thingy from the rear side of the lensboard and see if that does the trick. I'm not a fan of beselers, but I'll keep my big mouth shut in this case. Good luck.
