This piece of equipment was used at the Chatham Collegiate Institute in Chatham, Ontario, a secondary school which was founded in 1885 and closed in 2003. In 1851 the first school was established in the village of Chatham and by the late 1870's it was called Chatham High School. In 1885 the school attained the status of a collegiate institute, enabling it to obtain larger provincial grants and by 1887 a new school building had been constructed and the CCI was considered to be one of the most outstanding secondary schools in Ontario (it was destroyed by fire in 1946). In 1940 a new building was completed & again was considered to be one of the most modern educational facilities in the province. The school was closed in 2003.3.
