Re: Zone VI lens boards, there are different models of camera that have different sized lens boards. If it is the older Wista model, then the Linhof type board will fit. If newer Wisner/Calumet etc. then it would take a wooden board.

Check your shutter to make sure what size it is before buying a replacement. For example, it might be a 00 size shutter instead of 0. The skgrimes website has measurements.
