- The photo is Ernie Grow visiting my grandfather Jim Turnbull, my mother's father, in his basement shop on Patricia Avenue in N.D.G. (Notre-Dame de Grace), Montreal. They are inspecting the new copper boiler that was built by Boot Caulder (sp?) for one of his freelanced 10-wheelers. You can see the chassis to the right. The Boot Caulder company were coppersmiths for the major breweries in Montreal such as Molsons, Dow and Labatt.
