This image, and the accompanying blow-ups, are of the Huntley Manufacturing Company, Limited, facility in Tillsonburg, Ontario, Canada. Established in 1879, the Huntley Manufacturing Company was the world’s largest manufacturer of high quality grain and seed cleaning machinery as well as a major producer of peanut and coffee roasting machines. Note the arched roof.

Closeup. What is the event here? The Ford Model 'T' helps a little with the date. There appears to be either a very lightweight rail siding or construction track leading to the pile of dirt or sand. Is the Model T ON the track? Is this ground-breaking for an expansion? There is a ladder still up, so maybe it had to do with a new roof. Or, maybe it was just a sunny day and the boss wanted a picture.

This is a closeup of the roof. Are these simply skylights and/or vents, or could they be an early experiment with solar panels?

"...Rusticated concrete block, also called rockfaced concrete block, was made in a mold to create a surface texture that resembles stone. Its popularity as a building material peaked between 1905 and 1930..."
