Tea urn (Haywards Heath RH16)

Does anyone have, or have access to, a tea urn that they (or whoever) no longer want, please? We’re after one to use for melting a quantity of wax, so it would need to be one with a concealed heating element, please. Obviously it doesn’t have to be like the one pictured above....we’ll be grateful for whatever we can get, as long as it works & has a concealed heating element. Thank you very much.
