On Reneka's site a brief description of the company's history is given. http://www.reneka.com/expresso-brand.phtml
This thing was introduced in 1932. Steam produced the pressure, and the two big pots on the bottom swiveled inwards on hinges, to be filled alternately (I assume) from the big (filter?) basket, which locks in under the pressure group.
In this picture from Renka's downloadable pdf, you can see two in the middle of the slick early-modern showroom.
I thought of buying it for an ornament, but chickened out.

Stephen Duff
