Well, the modern "analog" meters do use Weston/D'Arsonval galvanometer. To make it into the ammeter a shunt is placed across it, which is why I asked about the shunt resistor.
But the bare system, the magnet, the pivot and the wire frame (coil) with the attached pointer is, well, the Weston galvanometer.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
