Here are a couple of shots of the VR-1000 and the DuMont scope. Check out

The scope was last calibrated in '67, but obviously is much older. It has binding posts for inputs, no coaxial cable inputs. Unfortunately the old calibration sticker was over the name plate, but the residue should clean up easily.
