At Continental we had B727-100's with -7 and -9 engines, gross weight was 160,000 pounds, we had 727-200's with the -9 engine with gross weights at 172,500 0r 175,500, the latter were ex Braniff aircraft.
We also had 727-200's with the -15 engine and a MGTOW of 198000 pounds.
Air Mike had some ex Alaska airframes with the -17 engine, not sure of their gross weight limits but I know it was higher still and they had auxiliary tanks.
