Good info except the why we call it 7ER. It was the international category when there was a domestic only category for it, since combined into one. Similar to why we have the 73N. There used to be 737 category at the same time that was the steam guage a/c (also i believe a 73G or similar for a while from my recollection when there were some glass cockpit 737-300s)
