What you'll see is a date code, possibly something like 'U1140F.' The first letter tells the year the camera was manufactured: in this case, 1980. It's an alphabetic code; A = 1960, B = 1961.T = 1979, U = 1980, and so on up to Z = 1985. The next 2 numbers tell you what month the camera was made, in this example, November. (the leading zero for the month code is sometimes omitted, so an A-1 with a code of 'Y362' would have been manufactured in March, 1984, for instance.) The following 2 numbers are an internal code that is irrelevant for determining age, but year and month is close enough anyway, IMO. (This internal code is also occasionally omitted based on reports from Canon owners.) The last letter stands for the name of the factory. In this case, 'F' stands for Fukushima which was the main Canon SLR factory for about 20 years from the early 70s until 1991.
