I have always gone by the "Major beam" having the U shaped casting and the smaller "beam" having the two straight strips of metal. Problem with google images is it will show pictures that contain some of the words and miss out the "major"
Easy way to check if it is a Major is by the valve chest facing the column, + section conrod and ringgear next to the flywheel as I have seen the basic beam with a U shaped bracket machined from solid on more than one occasion
