tdracer,
There were so many 727s built it's hard to keep them all straight. I wouldn't doubt your recollection at all.
Ours would mostly have been post-1973ish following the Northeast merger. The 100s and 200s from NE would have been older.
We had -232s for whatever that's worth...and about 9 or 10 -232As which had the aux fuel tank (6,000 lbs ?) and the Block 5 autopilot which was an improvement over the more common version with the pitch control via the turn knob...finesse required but you get used to it pretty quickly.
We had two 232As with winglets as an experiment which went nowhere as far as I remember. Those had the 40 flap position either blocked off or its use prohibited due to control rigging required by the winglets. All my recollections subject to "revision".
