Great machines!
I think the Cleveland is a Kirby machine.
No, I'm not talking about the Kirby division of the Scott & Fetzer Co. but rather the inventor, James B. Kirby.
Jim was born and raised in Cleveland and designed a number of upright vacuum cleaners. Before he introduced the Vacuette, he sold a prototype known as the Vital Rand.
And here is a bit of trivia. When Jim Kirby decided to market his first upright called 'The Broomstick' in 1910, he joined forces with three men named Black, Decker and Lamb. Black and Decker went on to produce power tools, and Lamb went on to form the Lamb motor company. In later years, Jim worked with Bill Orr, who helped him design the vacuum cleaners that became Apex.
That Cleveland should look great once it's cleaned up a bit. How about a step by step restoration.
The others are great machines too.
