Provenance:
From York County (York Region) Ontario, once a rich agricultural hinterlands, attracting early settlement in the last years of the 18th century. Located on the north slopes of the Oak Ridges Moraine, within 20 miles of Toronto, the County would also attract early ex-urban development, to be come a wealthy market place for the emerging household and consumer technologies of the early and mid 20th century.
This artifact was discovered in the 1950’s in the used stock of T. H. Oliver, Refrigeration and Electric Sales and Service, Aurora, Ontario, an early worker in the field of agricultural, industrial and consumer technology.

Technological Significance:
Simple plate fins, engineered for a press fit on the condenser tube, as in examples 1 and 3 were relatively easily achieved. The serpentine, soldered fin construction in example 2 represented a 2 nd or 3 rd generation of fin engineering, with higher conductivity and thermal performance. The manufacturing process for producing the fins and soldering them in place was a mark of the increasing sophistication of Canadian manufacturing methods, in place by the end of the 1930’s.
As manufacturing methods evolved the Canadian industry would move to non-ferrous tube and fin construction [copper], see code no. 6.02-7, and eventually to non-corrosive refrigerants, including methyl chloride and Freon 12. But for now this construction genre remained as the state of the art, an important snapshot in time.
