This is a nice Zenith 6D510 manufactured in 1940. This is a 6 tube AM radio. It has been electrically restored. This includes replacing all electrolytic and wax paper capacitors. All resistors were tested and any out of value were replaced. The tubes were tested and any weak were replaced. The power cord and dial string were replaced. After all of this the radio was aligned. I plays very well and is very selective. The cabinet is in great shape and has no cracks or chips. The dial lens and knobs are new replacements.
