Forgive the newbie question, but I might be jumping into the world of 4x5 monorail cameras due to a good deal that's come my way. It's a Calumet, likely a CC400. My potential purchase is coming with a lens/lens board/shutter, but I'm looking into other lenses. A good number of lenses I see for sale come mounted in a shutter and lens board with the lens board indicated as a "Technika". I'm getting confused by the specs available for new/old Technikas and various Calumets - can someone please confirm if a Technika (presumably fairly modern) lens board will be compatible with the Calumet CC400? Thanks!
