• Notes

• Kriesler Triplex Battery/Electric Portable.

  This completely new radio has the "go everywhere" convenience of the finest portable - the handsome looks of an expensive mantel set - and it's the ideal radio for the car, too. It's three sets in one. It has an ultra-modern "luxury look" cabinet, with its smart gold trim and gleaming two-tone colour styling. The ingenious "auto-strap" carrying handle blends into contours of the set when not in use and gives it that sleek, streamlined look.

  "Rotozone" dial - 24" square in area - gives the easiest tuning ever, rotates to find the State or station. This wonder radio can be used in over twenty different entertaining ways. (FROM MINGAY'S PRICE SERVICE)

  Colours available in charcoal/pink, burgundy/ivory, tan/ivory.

  Battery types: Eveready 733 and 495 or equivalent.
