This radio was made by the Philco Radio & Television Corporation of Great Britain Limited. It has a moulded Bakelite cabinet and was designed to be mas produced, costing £6 6s 0d. Its standardised design was used in several different models. When combined with a wood flour filler, phenol formaldehyde, known by its trade name 'Bakelite' after its inventor, Leo Baekeland, forms a useful mouldable plastic, with very good electrical insulating properties. It was the first plastic to be used for making radios.
