Mark S. posted:This item is not a train but it winds up and was made by Marx. It is a prototype model for a windup stationary engine that apparently would have been used to power various accessories. The flywheel is the same part used on Marx prewar steamrollers. The rest is hand painted including gauges, pipes, and a Marx logo. The base is marked "7-12-38, Erie, #1640". I'm not aware of Marx ever putting anything like this into production.
Very interesting find there Mark !!!
Looks Like Marx were diddling with a clockwork powered version of the Hess( germany) Dynamobil
I just happened to pick one of these up myself recently
