Hi! I'm looking for a lens board for my just-purchased Kaiser VCP 7002. The lens boards available new (4423 and 4424) say they are compatible with the 7005 (please see attachment) but not compatible with the previous system-V models. I'm pretty sure these boards aren't going to work with this enlarger. Can anyone point me in the right direction please? I'm pretty upset that I can't use my beautiful new enlarger.
