1)
The year of manufacturing is coded by the third capital letter of the serial number on the type plate:
S = 2002, T = 2003, U = 2004, W = 2005, X = 2006, Y = 2007, Z = 2008, A = 2009, B = 2010, C = 2011, etc.
Example:
Serial number: ARSH-0054, the 3rd capital letter is S, so the year of manufacturing is 2002.
