Here is an excellent and fully functional reproduction whistle for the Marx Big Loo. Nearly all the original whistles have gone missing. The mold was made from an extremely rare original part that was taken apart very carefully to make the mold. This item was cast in light green plastic. The whistle sound is exactly like the original which emits a loud and annoying "double tone" sort of like a toy train...OK thanks! There is no guarantee of a color match to any original parts
