Reply to "Old S Gauge GG1"

There might be terminology differences here.

The Imfield GG-1 body is not diecast. Diecast is pot metal, or Zamack, which is forced under high pressure into a precision two part (inside and outside) tool steel mold at liquid temperature.  Just like steam locomotives.  Very expensive to make for a garage operation.

The body of this Imfield S gauge GG-1 is made from epoxy resin, cast in a simpler type of single part mold, possibly plaster or RTV, like a slush mold. Much easier for a cottage/garage industry to make.
