As I have little inclination it has taken over 2 months to do, I just need to work out the aerial coil on the back panel, it has two wonder type plugs and a loop of wire. I am guessing it goes to the frame aerial somehow.
cheers Mark
No Mark - the frame aerial (L2) is used for MW, with the loading coil (L3) shorted out with the wavechange switch in the LW position, but when you switch to LW, L3 is put in series with L2 to incirease the inductance for LW. The 'coupling loop' doesn't connect to any part of the radio - it's provided to enable each end of the loop to be connected to an external aerial and earth to increase the range of the set when used at home rather than portable, and is inductively coupled to L2/L3.
As you will know, this radio was also produced as an 'all dry' battery table model, bearing in mind that in 1950, almost a quarter of homes in the UK still had no mains electricity. I can well recall the fierce opposition to pylons and overhead cables snaking their way acrosss rural England as there is today about the 'visual pollution' of wind-farms. Not everyone welcomes the coming of electricity back then!
Ever Ready, as a battery maker, along with the likes of Vidor, had a vested interest in promoting battery portable and table radios, and whereas until well after WW2, many radios had accumulators for the low tension, the production of 'all dry' receivers meant that Every Ready et al got the marker for LT, rather than the local cycle shop who often used to re-charge accumulators, but no doubt ended up selling the radio batteries too.
I was aged 11 when that radio went into production, and find the socio-economic historial aspect of radios such as this one of interst, as well as the radios themselves.
