Just as a matter of Interest
This date range is well before the Introduction of Decimal Currency in 1966
Shirley's salary in 1948 was 131 pounds per year ($262)
and by 1958 this had increased to 641 pounds per year ($1282)
These days people are not happy with less than seventy thousand per year !!
Naturally prices were quite different sixty years ago ... bread was $0.08 per loaf,
petrol was $0.10 per litre, a car cost $1500 and a house was just $12000 !!
