Find out if Lufthansa FRA or Air France ORY still kept their 727 simulators after retiring the type, for contract training. Royal Air Maroc, Air Algerie, Tunis Air, Iran Air, Lybian Airlines, and Alia used to do their training in Paris or Frankfurt. Been away from the 727 for well over 20 years from flying them, so cannot say. If they do, ask them how to obtain training, instructors and using their simulators.

In the USA, plenty of locations, sorry for you, but try Air Canada, they might still operate one for contract training.
