I can't see the pics for some reason. Split bus
panels were very popular here as the main service, we have swapped out hundreds. Mostly FPE but some GEs as well and a few QO. One house had a QO with 3 busses, first one of those I ever saw on a residential service. Most of our service equipment is outdoors and FPE made a 200 amp split bus outdoor panel that found it's way onto thousands of tract homes here. Of course DIYs and AC guys don't understand them and just plug stuff on anywhere they see a hole.
edit: I figured out the pics, seen a few of those too but the FPE was by far the most popular. A lot of times home inspectors will call those out for not having a main and we have to explain the 6 main rule.
