I have a Gaggia with this big brewer group and the valves etc all look the same. This Astoria is quite modern for such a group and still it seems the same as the very old ones. It is my assumption that one opens the top and spoons in coffee grounds and then opens one valve to allow boiler water to enter the chamber, then decant through one of the lower valves. there is also what appears to be a wand on the bottom as well and this one is a mystery. I don't think anyone has actually used one of these enough to analyze the worthiness of the contraption, but is is very cool looking and it attached to a flange on the boiler just the same way as a regular group.
My Gaggia with this group is in a box so I cannot do more than theorize about it at present...
