This is a standard bi-metallic thermograph to British Meteorological pattern. This one was supplied to Instruments Ltd in Canada. Has a 7 day clockwork drum with a range of what appears to be 0’F – 100’F. Has some wear and tear but rust free and no noticeable dents. Would make a lovely restoration project.
