Which switch is which?

I couldn't remember which devices were the oldest ones in a branch office where we planned to replace some gear.
You would think that somewhere in SHOW VER there would be a manufacture date of a switch or router.
After a long time staring at various output from SHOW commands a friend of mine "googled it for me" (see LetMeGoogleThatForYou)
and came up with this helpful information:
> Anyone know how to locate the manufacturing date a switch?
Do a "show version" and locate the System Serial Number.
The serial number is in this format: LLLYYWWSSSS
LLL = location of the supplier
YY = year of manufacture
WW = week of manufacture
SSSS = serial-id
Year codes:
01 = 1997
02 = 1998
03 = 1999
04 = 2000
05 = 2001
06 = 2002
07 = 2003
08 = 2004
09 = 2005
10 = 2006
11 = 2007
12 = 2008
