There are seat maps of DC 10 aeroplanes in the 1980s, with a three class configuration: first class, executive class, economy class.
Executive was Finnair’s name for business class at the time.
I am not 100% sure about this, but I believe F was in a 2-2-2 configuration with 12 seats and J was 2-3-2.
