I was working with a guy from South Carolina today, and he said that 
when he was in Torino Italty he picked up an expresso machine that on of 
the locals told him was a good home unit (about 1976). I asked for the 
name, he couldn't remember. Only that it was all brass and copper, has a 
little brass 'cabinet' rail on top, about a 2 Qt boiler, and a temp 
gauage & pressure gauge. When he got up to temperature and pressure, he 
turned the valve and got expresso.
Who can name that machine in two notes or less?

An antique Victoria Arduino (the original ca. 1905 espresso machine)? Nobody's "turned a 
valve" to make espresso since Gaggia invented the lever pump machine in the late '40s
Here's the famous advertising poster:http://www.musicman.com/0tiger/ard.htmlCorrection: here is a "retro" "Arduino" home machine, made by Nuova Simonelli, where the 
pump is started by a valve dial:http://lists.sweetmarias.com/mailman/listinfo/homeroast">http://www.nuovasimonelli.it/victoriaarduino/news.htmhomeroast mailing listhttp://lists.sweetmarias.com/mailman/listinfo/homeroast

Hey Jim,
He was specific about the gauges on it, and the little cup rail on the 
top. He said it read out in kPa, and was told to wait until the pressure 
was at the top of the green band. I'm not seeing that in the ones that 
you show.

Hi Ben,
I was sort of kidding with my first reply. 
Most everything about the machine sounds standard -- the pressure guage with a green zone, the 
cup warmer, etc. These are normal equipment on commercial and high end home machines. Also, 
most espresso manufacturers create decorative models with copper cases and cup warmer shelves.
The only thing unusual is the turning a valve to start the extraction. I recall a post by Roger 
Barrett on alt.coffee about "idrocompressione" machines that used a hydraulic press energized 
by the water mains pressure, instead of a spring lever or motor, to create the 9 bar used for 
modern espresso. These are rare machines, made until the 80s, but no longer. They would 
probably be started by turning on a water valve. One machine that used this was the Rancilio Z9-
AT. Unfortunately, I can't scare up a web page with pictures.

Okay,  Jim. I don't have a machine myself, but I figured you all might 
want to take a guess.

Ben, it's fun to guess. 
Trouble is, they're all fairly alike. For instance, I have a machine that's more or less 
identical to about a dozen other manufacturers' models; if someone swapped it out for 
one of those, it would probably take me a week to notice.
I guess what's needed for espresso machines is something like the "congratulations, 
we've lost your baggage" chart the airlines have, where you point out what it looked 
like. Verbal descriptions are hard to work from.
