Large Marconi TF1370A wide range oscillator which will fill quite a bit of workbench space compared to more modern instruments. This features a large circular tuning dial with which the frequency is set, a working level meter & 2 indicator lamps. This would have been used for testing audio equipment & also radios in a laboratory or production line environment. This isn't actually a radio itself but you could pretend it is because of the large tuning dial.
