Not so much the aircraft manufacturer as the individual airline.
All airlines that I have worked for require "gear down" at the final approach fix, with approach flap (intermediate) setting, and landing flap selected when on the final descent to the runway. Note that this could be from base leg or from final. I was trained this way by (the original) Pan American and it seemed to work very well for the B707. Later on in the TriStar, same procedures. This has the added advantage for the new F/O's in that they need only call for landing flap when required.
Simple concise procedures lead to safety. Others try to reinvent the wheel, which makes no sense whatsoever, IMHO.
