|NOTES||Being a BV20 this is, of course a Birmingham model, however there was
no equivalent London model. Londeners still had the
D18T which was essentially the same circuit as the BV20C but in a much
narrower cabinet. Thus the BV20C is one of the few, perhaps only, television
models where a cabinet was designed for one specific region.
The reason for the different cabinet of the BV20C was probably to reduce the number of chassis variations. The London D18T took the equivalent table model, the B18T or LV20, mounted the chassis vertically and bolted an additional horizontal chassis to it. However by making the D18T cabinet wider they could insert the standard table model's chassis in the cabinet and that is what they did with the BV20C ; it is the same height D18T but with the appearance of having put on some weight !
It seems that the set may have also have been made available with a purple screen filter to give improved image quality under ambient lighting.
There don't seem to be many BV21C's knocking about. This may be partly due to the fact that within little more than six months the model was replaced by Pye's newer model, the LV30C.
