I'm not familiar with Zone VI cameras but did notice that Keh has a ZONE VI CLASSIC FIELD BAG BELLOWS in stock for $84 and a WISTA M BAG BELLOWS for $31. http://www.keh.com/Camera/format-Lar...c=79048&r=WG&f

If your project will be extensive one, then you might consider acquiring a camera that is able to handle all situations. A Toyo/Omega 45C is able to deliver all the movements you could possibly need (e.g., 120mm rise on both stardards) and they are very inexpensive in todays market. It's a very robust camera that's light (9lbs) and quickly disassembles into 3 pieces (flat standards and bellows, rail and tripod block) permitting it to be backpacked. Add a Sanford & Davis tripod (~$40 new) and you will be able to photograph any interior with comfort and ease.
