Be careful when looking for a Marx William Crooks Engine.
The one you described is the most desirable and attractive of the offerings, and Marx smoke units
do work like crazy.
HOWEVER, a mechanical (ie: wind up) version was offered, and this one turns up more than the electric versions.
Further during the final years of Marx train production in the early 1970's, a revised , electric Willam Crooks was offered, but lacked smoke and some other decorative features.
