Galloni Fusus casting machine

I’m having a difficult time trying to find out which casting houses
in the U.S. use the Galloni Fusus casting machine. I want to see if
my models come out denser and with no porosity. I even tried
contacting Galloni in Italy, but they just forwarded me to Gesswein
who won’t reveal any of their customers. I already know that Tiffany
operations use this machine, and at least a couple of retail
jewellery shops in the States use it too.
