Context

Country: Canada
State/Province: Ontario
Period: 1970's to early 1980's
Canada: An instrument of a type used by the Meteorological Service of Canada, possibly in its calibration laboratories. Part of a large collection of meteorological instruments acquired from the Meteorological Service of Canada (previously Atmospheric Environment Service) by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out).
Function: A handheld magnifying device, possibly used to ready scales or levels while calibrating or verifying instruments in a laboratory.
Technical: A magnifier with a hammerline finish suggesting a date of manufacture of the 1970's to early 1980s. The AES label suggests that the magnifier was acquired by the MSC after 1971, when that organization became the Atmospheric Environment Service.
Area Notes: Unknown
