c.1959/60 Mitsubishi 6X-870

Shirt pocket radio, thermoplastic cabinet
4 1/8 x 2 13/16 x 1 1/4 inches / 105 x 71 x 32 mm
Six transistors (Hitachi), one standard 9-volt battery
Manufactured for Mitsubishi by Shirasuna Denki Mfg. Co. Ltd., Japan?

May have been released in late 1959. Small and slim, with a painted metal speaker grille.

On his Flickr page for the 6X-870, collector Michael Jack states that Mitsubishi didn't produce its own radios -- rather, they were made by another manufacturer for Mitsubishi, most likely Shirasuna Denki, and possibly other manufacturers as well.
