American Flyer Whistle 568
Accessory: Steam Whistle Billboard
Materials and Features: The Number 568 has a plastic housing – this was an update to the metal versions produced from before WW II through 1955. Inside is a motor driven blower that sends air through a two note whistle chamber. The resulting sound is a good impression of a locomotive steam whistle and the motor noise adds a satisfying sub audio grumble.
Predecessors include: number 577 and number 566
The prewar 2029 whistling billboard that Gilbert inherited from the American Flyer Manufacturing Company morphed into the 577. The 577 became the 566 and both had sheet metal housings. The 568 introduced a better looking and probably less costly to produce plastic housing
There is no Service Manual listed for the 568 but the 566 manual Form 1645 can be used.
The 568 whistle was produced in 1956 and had a green plastic base. The whistle was different from earlier years as Gilbert continued to move towards plastic materials. The picture on the sign was of a northern railroad. The whistle came with an operating button and was hooked up to a transformer for the model railroader.
Gilbert produced approximately 11 different type of whistles and/or billboards. They included:
The primary whistle differences were a whistle vs. a horn and the billboard imagery. Often times the billboard pictures featured other Gilbert products such as erector sets or chemistry sets. The American Flyer Whistle 568 was a fairly normal version of the American Flyer Whistles.
