Hi, I came across this lensboard with adapter on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7556021648&fromMakeTrack=true Does anyone have any experience with this kind of lensboard. Any idea what the inset board would fit. I'm wondering if this would allow me to interchange lenses between my Cambo view and either my Crown Graphic or my Toyo 45A. Thanks!!
