History:
Als National Toy Company gegründet, stellte National zunächst Spielzeug und mechanische Kleinteile her, Die 1916 in National Company Inc. umbenannte Firma produzierte ab 1924 Radiobauteile für den "Browning - Drake broadcast receiver kit" und "Velvet vernier" Skalentriebe.
Unter Leitung von James Millen begann National mit der Entwicklung immer leistungsfähigerer Kurzwellenempfänger, der "Thrill Box" ab ca. 1927 folgten die SW-5 und SW-3 Audionempfänger.
1932 brachte National mit dem AGS, der "aeronautical ground station", den bis dahin leistungsfähigsten Kommunikationsempfänger auf den Markt, bereits ein Design mit austauschbaren Spulen und einer Feintriebskala. Es folgte, entwickelt mit Unterstützung durch Herbert Hoover, im Herbst/Winter 1934 der HRO, der als Kommunikationsempfänger bei Funkamateuren und im kommerziell - militärischen Einsatz gleichermassen Erfolg hatte. Das Konzept mit den in Einschüben befindlichen Steckspulensätzen und dem PW-Dial, einer Feintriebskala mit in kleinen sternförmig angeordneten Fensterchen angezeigten blieb noch über die Kriegsjahre beibehalten. Erst das Nachfolgemodell des in verschiedenen militärischen Varianten eingesetzten NC-100 in der A-Version war mit einer "direct readout" Skala ausgestattet, beim Bandwechsel waren die Spulensätze nicht mehr umzustecken sondern wurden in der beweglichen "coil catacomb" im Gerät in die richtige Position gebracht.
Nach dem zweiten Weltkrieg entwickelte National neben kommerziellen und militärisch eingesetzten Kurzwellenempfängern auch Amateurfunkempfänger in verschiedensten Preisklassen. Man verpasste den Anschluss an die moderne kompakte und leichtere Gerätegeneration.
Mit dem HRO-500, dem ersten in Halbleitertechnik aufgebauten Kommunikationsempfänger mit Synthesizertechnik, brachte National 1964 nochmals eine technische Innovation auf den Markt.
Nach dem Firmenbankrott 1969 produzierte National noch für einige Jahre im Rahmen staatlicher Verträge militärisches Gerät, konnte sich aber nicht mehr auffangen. 1991 kam des letzte Inventar unter den Hammer.

Milton Lesser (born August 7th 1928 in Brooklyn, NY, died February 22nd 2008  in Williamsburg, Virginia) was author of (science) fiction stories and wrote also under the pseudonyms Stephen Marlowe, Adam Chase, Andrew Frazer, C.H. Thames, Jason Ridgway, Ellery Queen, Lee Francis, Darius John Granger, Ralph Burke,
Alexander Blade and S.M. Tenneshaw ...

In 1947 (or 1951?) he wrote (as Stephen Marlowe) the short fiction "Somewhere I'll find you" which was issued in Germany as "Jagd durch die Welten" {Hunting through the worlds} in 1966 as no. 468 in the "utopia" SF series.

The artwork on the German front page (painter unknown) shows an unknown or fictive NATIONAL tv set:
