Starting with underlined first-V, a bar is for production year

2012. The next bar is mark on top of second-V is for year

2013. The next bar is mark on bottom of second-V is for

year 2014.The next bar is mark on top of f is year for

2015. The naming pattern continues with consecutive

characters for later years.

3.

f is the week of production. The big character of A~Z is for

the week of 1~26, and small a~z is for the week of 27~52.
