We still have the old style kerosene lamps that my great grandmother left too us. I THINK the last time we replaced the wicks we took them to the local hardware store up here who oddly enough still had some kicking around.
Get in touch with an antique store, they may have info on where to find the burners or the wicks.
Just a thought.... There is a jeweler's supply place in the basement of 55 Queen St. E, TO, that sells small lab type alcohol burners (about the size of palm of your hand) for wax modeling... Might want to try there.
