It's possible that it was an early production model 52 but unlikely since the 51 came first, sometimes Philco would have a new chassis and model ready for production before introducing a new cabinet design, sometimes it would be a new cabinet design with an old chassis like the model 21. Philco was a company that didn't let grass grow under their feet before introducing things.
