The Inglis is more likely made by Speed Queen, although it is based on a British design.
The "rinse-o-matic" is VERY interesting though as it is much closer to the UK Hoovermatic than the US one - bear in mind the HMDL has a heater and the Rise-o-matic does not. Also the Uk version was only in white (see the link for a recent ebay auction). If this has come up on ebay or any other site for sale it would be well worth grabbing - it is very unusual
