I saw a post a long time ago where it was mentioned that the 727-100 had an oval inlet for engine #2, but that the 727-200 had a circular inlet for engine #2. The fix they mention only applied to the 727-200 and -200F not the -100 and -100F. On my 727-100 Base Pack, 727-200 and Freighter Expansion models they (supposedly) look as they should. I have not had a look on www.airliners.net to verify that.

Hope this helps.
