Various collections of Charlie Chan radio shows are available through a number of sellers. None are "commercially produced," and, I suppose that all could be called "grey market" products, but, as there has never seemed to be any other interest in putting these old shows together for sale, they are the ony source. You might find what you seek at our Charlie Chan Links section elsewhere at this site. Also, CDs of Chan radio shows pop up with regularity on eBay.
