It lists the normal "Focal Lengths" for common formats. Converting the mm to inches may help you find and old brass barrel lens of the correct focal length. But, I'm going to guess you really want a mechanical shutter for starters? Ebay is your friend. And you might find a decent starter lens/shutter here on APUG or at http://www.largeformatphotography.info/
You can also start the camera and use a pinhole as your lens. Once everything is up and running, replace the pinhole with a standard lens/shutter.

Hand holding ;-) . . . in eBay's "Cameras & Photo" section try a general search for "lens shutter" or "brass lens" etc. See what pop's up.
