Remember, the original Lawrence Tube renamed Chromatron was developed as BOTH one and three gun CRT's by Chromatic Television Labratory Inc. starting in 1951. Dr. Lawrence partnered with Paramount Pictures and Chromatic was a division of Paramount. Chromatic always knew that a three gun Chromatron would be considerably brighter then a one gun, but the one gun version received all the interest because of the potential simplicity of operation and lower manufacturing costs. Prototypes of both one and three gun versions were made through the years, then Sony bought the license and development rights from Paramount, first in 1961 and 1964.
