Above my Bunton Model 12-35B, powered by a Briggs & Stratton "High Inertia" Flywheel engine. Below, sensible warning information posted on the front.
The machine has a small (12 inch) blade. Two openings at the front of the deck allow it to bring heavier growth into contact with the blade, so it can sever small saplings. By today's consumer safety standards, no one would allow a blade to be uncovered like this, but from an engineering perspective it makes the trimmer really useful for handling brush. While its small size seems to make many folks on the web believe this model was designed exclusively for cemetery work, the ad below indicates that it was intended as a general lawn trimmer.
It turns out that the company's Ontario distributor was Duke Lawn Equipment Limited. Coincidence?
The mower also proved perfect for Kentucky blue grass, since it didn't cut it too low. This brings us to Louisville, Kentucky, best known as the home of the Kentucky Derby, Kentucky Fried Chicken, and Louisville Slugger baseball bats. (In 2015, the Louisville Slugger Museum was named one of the most beautiful factories in the world. It placed #12, and fourth among American factories.) It was also home to W. Price Bunton, who became a distributor for Goodall rotary mowers in 1948. That same year, the manager of a Louisville cemetery approached Bunton with a request to develop a mower that would be compact enough to trim grass between headstones. He and his two sons came up with a successful design, and founded the Bunton Company. Six years later, the same cemetery manager asked them if they could produce a high capacity mower that was also maneuverable. This was the seed for the Bunton's premier product: the wide-area, self-propelled, walk-behind mower, a.k.a the Lawn Lark. (Sadly, they never offered a Sod Sparrow, a Grass Goose or a Turf Turkey.)
