We had our first telly when I was twelve years old. It was the Murphy V-530 shown half-way down the page at the link. We (that is, me and my sister) were forbidden to touch it! And I can still remember the first programme we gathered to watch - Percy Thrower's "Gardening Club"!
Those were happy days. Britain was still a manufacturing nation then. National Service was just coming to an end (unfortunately). And we had V-bombers on fifteen minutes stand-by 24-hours a day!
