Those sets aren't too hard to find, but I've never seen the DC version.  Unfortunately rare doesn't always means it's worth more, and I suspect that's the case with your radio.  I can't recall offhand what I sold my AC version for, but without pictures of the cabinet and chassis it's impossible to even guess what yours might be worth, although I suspect it's less than you're hoping

A few years ago cathedral radios that would have sold before I made it to my table don't garner near as much attention these days

Also post a pic of the Zenith, in nice condition those are very nice looking cabinets.
