The significance of this specimen, like 019, rests in its evolutionary context. It is part of the dynamic, rapidly changing pattern of developmental events that saw the Canadian refrigeration industry move beyond its crude, early offerings to the households of the nation and do so in a period of much less than two decades. Of special significance, technologically, is the dramatic tansition from the crude designs of the 1920’s and 30’sto those of the 40’s enabled by new materials science and newly informed engineering theory and practice.
