The T20AW may well never have existed and simply been a misprint. the 'AW' indicated "All Wave", a reference to a television that included a radio which the T20 did not.
Models T22 and T24 were shown at the 1938 Radiolympia.
The T50, T52 and T54 were shown at the 1939 Radiolympia and may not have actually entered production.
