"Oddity"
Hi Alex, they are the UK Hotpoint Twintubs, first produced in 1960 using the agitator principle from their wringer machines...One of the UK`s top 3 laundry brands, they switched to the Spiralator agitator in the mid 60`s, great machines and where also exported to Australia etc,
The Impeller style twinies here where mainly Hoover, although we had Rolls models with the impeller in the base, the best base action machine I find is the Servis Powerglide, which uses a large angled impeller in the corner of a dipped tub - the vortex it creates is such you can stick your hand in it!!
