Serial number 104NY**** on a Citori: N = 1977? No — on Citori, first two digits are model, then letters. You must check model-specific layouts. 3.2. Model-Specific Serial Number Formats Because Miroku makes many different actions, the position of the date code varies.

After Z (2010), the sequence restarted at A (2011), B (2012), etc.
