Made by Louis Marx Co. in Great Britian, the Astrophaser is essentially the same gun as the Sound-O-Power Astro Gun also made by Marx . This practice of representing the same toy in different guises was a common one with Marx, whose Flash Gordon Radio Repeater, first made in the 1930s, was later reissued in the 1950s as three other different guns. The Astrophaser cost 8.73 pounds. It is 12 inches long.
