This instrument is a d'Arsonaval type moving coil galvanometer and not the Kelvin marine galvanometer as suggested by Green and Lloyd, it was also known as the recorder pattern galvanometer, presumably because the movement designed by d'Arsonval was probably based on the moving coil movement of the Kelvin syphon recorder.
