Our new USA member, Tom Guest, has uploaded some nice pictures to this model Airline 62-158 (WG24 Series 7D) which was sold by the mail order and department stores Montgomery Ward - but made by an other company. Tom also enhanced it with some data like dimensions, material, shape etc. I added the brand Airline.

He also uploaded a photo of the sticker which shows the patents for RCA and Hazeltine. For getting a further "picture" about the date of design I checked the last RCA patent - just to see that it was made by the German Georg Seibt of the Seibt radio factory in Berlin. This US patent of July 19, 1932 (1,868,443) is about an "Electric Discharge Tube", which was filed in Germany October 24, 1913. Here he is assignor to Radio Corporation of America (RCA), Delaware.

There is a complicated story behind all this and has to do with Telefunken which dominated Germany's set makers at that time - sometimes to the ruin of them (Huth etc.). The main reason was the Robert von Lieben patent of December 1910 when he claimed the amplification for the triode of de Forest who has not thought of this claim - but only as Audion. He has written about amplification but did not claim it.

Still now most of the collectors in Germany believe the story that von Lieben has invented the triode in 1906 when he unsuccessfully tried to get amplification by a man high device as a cathode ray relais. It never worked out. Facts don't seem to matter. At the beginning purposely the two complete different ways were melted together for the public and it stays like this besides all proofs to be wrong. Here is a translation of my text which I published in 1989 (different wording and without the part for semi conductors).

By the way: Aaron Montgomery Ward (1844 - 1913) is regarded as "inventor" of the mail-order industry. He started in 1872 in Chicago. His most interesting story is told at Wikipedia. His business collapsed nearly 90 years after his death in 2001.
