Notes;
The images seen here were taken of the radio following its restoration.
During the restoration of the chassis originality was the key point.
The cabinet as seen here is all in original condition.

The radio can  resolve 3 really strong stations on Long Waves, including RTE, BBC R4 & a French station, and about 3 more quiet ones. Lots of strong stations on Medium Waves and it is quite easy to resolve them with careful use of the fine tuning control and aerial capacitor. On MW the Reaction control hardly needs adjustment, it is just left fully anticlockwise. On LW the reaction control has a more pronounced effect and some adjustment is an advantage as you tune across the wave band.
Volume is very loud , you need to back off the aerial capacitor and detune slightly to get a reasonable comfortable listening level. This is easily the best TRF wireless set I have come across. All in all a very good radio and quite easy to operate with the ganged tuning control and fine tuning capacitor.
