Olympian Masters ?

I am looking for a list of Olympian Masters and what Olympics and events they particpated in. If you have such a list or know where one is, please let me know. Individual anecdotes are OK too. Background: I want to write to "Splash" magazine and ask them to feature some of the people on such a list when they write about great swimmers. I'm tired of reading (and having my kids read) about so-and-so great swimmer, who got to the Olympics, did great, and now swimming is behind them (i.e. they don't swim anymore). On the "mission statement" of Splash, they give lip service to a lifelong involvement with swimming, but they never seem to come up with an example of such a person. wiredknight
