Trusty Incubator made by the M. M. Johnson Company of Clay Center.
Nationally successful, the company produced more than 100,000
incubators and chick brooders in 1910 alone. In 1925 Johnson
started radio station KMMJ in Clay Center as a service to farmers
and as a way to sell more incubators. This incubator was used
on the Hesson farm near Unadilla.
