I have inherrited a Fleischmann Ice Electric Locomtoive from father in law. I t is not running, i took it apart and discovered one of the brushes is missing. I would like to replace it and have researched and found the brushes on line but i need the cap that holds the brushes and spring in its holder. I cannot identify the Fleischmann model number, no paper work found and not indicated on the locomotive itself. the class number on side is 401-001-2 . I think the locomotive is about 15 years old. Can anyone direct me to a site where i can either order the brushes and "Cap" (holder) or where i can try and identify the fleischmann model number. Thank you.
