 A very handy Cossor Valves station guide from the 1930's priced at 2d.  Contained information on 44 stations and even had a spare panel on the back for adding your own.  Funny that they should even mention whether the announcer was a man or woman!

"Distance, tone and power are each largely dependent on the efficiency of the valves in your Receiver.  Experienced listeners always choose Cossor Valves for their high sensitivity and the perfect reliability which enables them to obtain the fullest enjoyment from radio broadcasting.  Get the most from your set.  See that it is fitted with Cossor Valves for capturing those distant stations with brilliant tone and wealth of volume.
"Cossor Screened Grid Valves have an abnormally low inter-electrode capacity permitting the highest effective amplification.  They are available with metallised Bulb [sic] giving more effective screening with improved selectivity and stability.  Cossor Detector, LF and Power Valves have multi-point filament suspension and all types are built on the Cossor system of interlocked construction ensuring freedom from microphonic noise, consistent performance and long life."
