The Manx Museum has a network of wonderful "Friends" and all the small museums, like the fabulous Nautical Museum here in Castletown (and the Castle, the Old Parliament and Old Grammar School here too) have escorts who take you round and tell you all the background, the history and those little stories you would never otherwise know about. That is one of the reasons the Manx museums are so good. they are brought to life by the enthusiastic guides.
A retirement occupation for Ian, maybe?
