Pennington and Baker were manufacturers of school and office furniture. Located at 81 James St. Hamilton, back in the day they were the sole manufacturers in the Dominion of the “automatic” or self-folding school desks. The success of the folding desk was so remarkable the company was hardly able to keep up with the demand. At the time the top folding study desk was purported to be the strongest folding desk in the world. The company also established a name for themselves as manufacturers of the telephone boxes for Canada. Could this T square here have been used to draft the original design of either of these historical items?!
