Hi Matthew.
Great find.
They are certainly very smart looking spinners - love the chrome top rim and blue spinner lid.
Information courtesy of one of Chestermikes brochures:
this spinner was on sale alongside the Hotpoint 1502, Empress, Countess, princess and second version supermatic, as well as the 'Hotpoint Spin dryer De Luxe'. The latter was the tall, rectangular shaped spinner with a pump, whereas your new purchase is the gravity drain ' Hotpoint spin dryer'.
The de luxe machine was a 3100rpm spinner - effectively the spinner part of the supermatic, but cut off from the washtub.
The standard machine was slightly slower, with a rpm of 2850.
Hope the info above is useful.
Qustion for you - do you know the model number of your new machine? The rectangular spinners were model 1012, but i have never found out what the cylinder machine is.
congratulations on a great looking machine.
