Two old Marx classics. The 1666 does not have a smoke unit (looks like there never was one). But it does have a double reduction motor which has been fully serviced. Lights and runs forward/reverse as it should. Shell has been repainted custom two-tone. Also, the rear truck is an old-school American Flyer replacement. Marx 400 motor has been fully serviced and the engine runs forward-only like a rocket. Shell has a two-tone custom paint job. Nice looking duo. PayPal only and no international. Thanks!
