There were only a handful of 737-100s built (mostly for Lufthansa) and I believe they're all out of pax-carrying service now. There may be more MD-81s around. Not sure in N. America who would have any. Most I think are 82s (hot and high) and 83s (longer range).

I do understand that no carrier might have operated both and I also understand that these aircraft are from two different time frames (eras). Thanks to all. JC
