Hoover Wringer Washer
This was the second edition of the Hoover (hand) wringer washer. In Canada I believe you had the model 0308 which was the equivalent of the UK0307 which was the first model. Introduced in 1953 this model had updated styling, larger capacity, an emptying pump and wheels. Two things surprise me - firstly it is designated model 0319 the same as the UK, normally they were slight variations in the model number and it is designated as North Canton rather than the Canadian company - Hamilton, Ontario (?).
This is pretty much identical to the wash tub of the first Hoovermatics (with rounded corners and no controls on the top), the pump is permanently engaged and runs whilst the machine is running. The fill hose had a specially tapered end which you inserted into one end of the short hose behind the wringer when you wanted to empty the machine which extended it into the sink.
Apart from a minor styling update in the 1970s (when the cabinet was squared off) this design carried on pretty much unchanged to the end of the 1980s (the wringer models dropped around the very early 1980s but it carried on without a wringer) when it could still be paired with an independent Hoover spin dryer to make the "twosome" twin tub
The serial number seems to run in the same sequence as the UK models which would indicate this machine was manufactured in around February 1954
