There was an article in either "The AWA Journal" or "Antique Radio Classified" that dealt with the development of the format and the development work was underway before WW-II. First plastic boxes hit the stores in the late 40s, like all of the other war delayed consumer products. I do not have the date of the article readily available. I do not remember if there was any commercial release of 45 rpm records either large or small hole pre war.
