Marx train 400 windup smoke puffer

I got this for $32.00 at a loco hobby store, this train was made in the mid 1950's. Still works.
This train has a rubber balloon that is hooked up to the smoke stack, it also has the smoke cap, that is always missing.
You put backing powder in the stack then put the cap back on the stack then wind the train up, let it go, and out came the backing powder AKA the smoke, and the train went around the track smoking and ringing a mechanical Bell. This is a very uncommon train, kina rare.
Keep in mind, marx and other toy train companys has more better electric smoke.
So this train was not that popular.
