Yes indeed! The original name of the brewery was the Kuntz Park Brewery. It was sold by the Kuntz Family to Carling in 1927, I believe. The Carling Brewery was still operating when I went to university in Waterloo from 1962-1967, but has since been demolished. The original Kuntz family home, however, still stands on the same location, and is now a funeral home.
Is your picture of the delivery wagon an original? Do you have the ability to scan it? If so, I would love to see a scanned copy sent by e-mail.
Tom Fischer (My great-uncle, Dr. William Joseph Fischer MD married Carolyn Kuntz in 1908. Her grandfather was the founder of the Kuntz Brewery)
