I have what I know is a prewar OO Lionel steam engine, shell tanker, box car and a caboose. The engine is missing the motor and tender whistle. Other than that they all seam to be in good shape. As I am not into collecting Lionel I figure someone who does may enjoy them more than myself. Problem is I cant find any prices as to there worth ? Anyone have an idea or know where I can go to find out ? Thanks for any information or advice Terry
