Bigger is often better and this Amp Meter is large. Possibly a school science lab item used as a teaching aid and easily visible from across the class room.
A vintage item for decorative purposes. Not tested, so I would presume that it isn’t in working order though everything seems to be present including the finger gauge.
Nice plywood construction with cream display board and perspex panels revealing the mechanism.
Size 42cm wide, 40cm high base measures 25 x 15cm
