The following is from a web page I can no longer find (but I kept a local copy of it):

How to determine the age of your EOS camera or lens
Because they are chronological, serial numbers usually do tell the approximate age
of a Canon SLR or SLR lens, but Canon Inc. has never put out any sort of public info
about it. However, there's another way to get the information: look inside the body's
film chamber for an alphanumeric code printed in black ink on the black surface of the
film chamber. You may have to hold the camera under a strong light to see it. 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. (The factory code is rarely
omitted, if ever.)
Starting in 1986, the year code was restarted with "A" again, but the factory code
was placed before it. Now that Canon SLRs are no longer manufactured at Fukushima,
you're more likely to see a code starting with "O" for Oita. So, for SLRs manufactured
in 1994, you might see a code
Starting with "OI" followed by the month code.
Incidentally, the same type of code is printed on the back of most EF lenses as
well, typically in small white characters on a black baffle in the rear lens mount.
Since Canon's SLR lens factory is in Utsonomiya, you might see a date code starting
with "UG" for a lens manufactured in 1992, for example. Previous to 1986, though, the
lens date codes did not include the factory letter.
A * 1986 B * 1987 C * 1988 D * 1989 E * 1990 F * 1991
G * 1992 H * 1993 I * 1994 J * 1995 K * 1996 L * 1997
-------------------------------- end copy ------------------------------------
I hope this is some help - so ON1014 means made in Oita (O) in 1999 (N) in October
(10). The 14 apparently has no real meaning, but the month is probably close enough.
