The General Alarm Fire House is one of the Marx toys that work well as a train accessory. Trip Riley showed his in the Greenberg's guide with a car, truck and ambulance. The ambulance probably did not come with his set, it is not rubber stamped as the car and truck. In my set neither vehicle is rubber stamped but are likely the original vehicles, coming from the same seller.
I have learned that prewar sets had the rubber stamped vehicles and postwar sets were not stamped. Also, the set came with the solid side truck as shown but sometimes came with the slotted side body.



Here is the open box with insert and instruction sheet.



Box top reads "Turn alarm lever and hear the gong ring and see the fire cars shoot out of the station".
