VINTAGE RADIO VALVE, TP22 BY MAZDA MADE IN ENGLAND NOS ex PYE FACTORY
I have had in my possession for many years, a number of early radio valves. They had been in storage at one of the Pye factories in Cambridge and cleared out some 30 - 40 years ago. Most are in their original packaging and I was reliably informed that they are un-used, (New old stock, [NOS]). These valves are being listed as un-tested but I will be able to identify which ones are mine!!! It has been known for some dishonest characters to return blown valves as if they were the ones just purchased for credit...
Overall height of box: 6 inches
Condition: excellent, no chips or cracks appears unused
NB If you look at the last picture you will see that recycling was recommended 100 years ago!
