Traditional Air Whistle
You are looking at a great Lionel steam tender that makes anything into an instant Christmas train! Turn any of your steam engines--from 1946 to now--into a Christmas Express with this festive tender complete with whistle (just like the old postwar ones). It is working and in great shape. It has no box.
Maybe you want to add whistle to the steam engine on your loop; maybe you want to replace a broken one (heck, this is cheaper than a repair!).
CONDITION: Has been lightly used, but looks like new. Rollers show just a little bit of track time. Tested and works.
