Nice find. It looks like it's in good shape. Was this a process camera, designed to ride on rails?

If you want to use it as a portrait camera, I'd look for an old studio stand with two pillars, a tilting stage between them, and a heavy iron base. In the meanwhile, something like a Black and Decker portable workbench might do. I know someone who used one to take his Lotus 20x24" into the field, where the rolling cart was a bit impractical.
