• Notes

• Hoffman model P410 is a battery operated portable AM transistorized receiver.The Hoffman model P410 "Home & Travel All Transistor" AM Radio with a handle was released together with P411 which has a built-in solar cell for batterie (Accupack) charge on top of its handle. On both, the back kick stand is marked Sony because the cabinet for the Home & Travel was supplied by Sony - then actually still Tokyo Tsushin Kogyo Ltd. but already having decided to become an international brand. You will see some similarity with Sony TR-6 - and it might be the only cabinet Sony made for other brands.

  The set was about half the price of the Solaradio which was one of the earliest solar-powered radios - and with the then very expensive rechargeable batteries ($ 9 for apiece). See the sibling with solar panel for $ 159. Both Hoffman models came 1957 in 5 different colors - which were put in front of the actual model designation. The B-P411 radio appeared on the cover of Popular Science magazine in August 1957 - in black color. The Hoffman P410 and P411 series radios were available in: Seal Black (K), Desert Sand [beige] (B), Turquoise (T), Calico Red (R) and Circus Pink (P).Colors: K-P410, B-P410, T-P410, R-P410, P-P410
