Rita, The cord is a standard electrical appliance cord which you can purchases from any electrical wholesaler (where electricians go to buy electrical fittings cables etc). If you cant buy the cord made up you can definitely buy the plug, socket and cotton covered cable and have the cord made up.
I know this is a very old post but its one of the few times a Lanco Vapor controlled Kettle comes up on Internet searches. I need a new thermostat for mine...
