How do you know the manufacturing date on the BG-12? I’m quite curious.

There’s little clocks on the back that tell you. My dad told me what those are for.

Ah thanks


Interesting! If that is correct, then my BG-12SL was made on Febuary 2nd, 2013.

If i am correct… My BG-12SL was also made on February 2, 2013… I guess our pull stations are siblings… lol
