You seem to be thinking in 35mm SLR system camera terms about lenses. In large format, there is no relation between the brand of the camera and the brand of the lens with very few exceptions of specialized cameras with helical lens mounts. A Calumet camera doesn't require Calumet lenses, and there is no particular advantage to using Calumet branded lenses on a Calumet branded camera, since they are both rebranded items anyway (old Caltar lenses were made by Ilex mostly, Caltar-S by Schneider, and Caltar-N by Rodenstock). Pretty much any lens will mount on any camera--Schneider, Rodenstock, Nikkor, Fujinon, Caltar, Ilex, Wollensak, whatever. Each lens comes in a shutter typically, and there are three basic sizes of modern shutters, and then there are older shutters that may require that a lensboard be drilled to order, which is a normal and not terribly expensive thing to have done. It's not jerryrigging--it's just how it works!
There are lots of good older lenses out there that are very affordable. If you like modern lenses, look for something like a Schneider Symmar convertible from the 1970s. These are similar in design to the latest modern plasmats and are generally single coated, and are very economically priced.
