One of a number of pocket radios almost certainly inspired in cabinet design by the 1959 Standard SR-D210 — another was the Daylite TN-603. These radios were strikingly beautiful in their unique usage of reverse-painted plastic — adding a 1.5 mm (1/16") lip around the edge of the reverse-painted area gave the clear plastic face the illusion of extra depth. Their cabinet dimensions also gave them an ergonomically perfect fit in one's hand.
While this Harpers and the Daylite TN-603 look nearly identical in cabinet layout, and both make use of Hitachi transistors and a number of other components in common, they have different circuits.
