BAIRD STREET N 2mm Scale/9mm Gauge Baird Street is the latest all-action T.V. series. It is broadcast on Channel Tram and is suitable for viewing by children of all ages! The model consists of an old television cabinet from which the equipment has been removed. It now contains a scene depicting a British city centre with operating tramway in the post-war period. Safety Note: If you want to convert an old television set Baird Street style, remember that a television tube is a vacuum vessel which must be handled and disposed of with extreme care.
